[blackcat] L2 Ehlers Optimum PredictorLevel: 2
Background
John F. Ehlers introuced Optimum Predictor in his "Rocket Science for Traders" chapter 20 on 2001.
Function
As we have seen before, the majority of the code involves the computation of the period using the Homodyne Discriminator algorithm. Once the period has
been computed, the Optimum Predictor is found in just a few lines of code. First, the minimum-length Hilbert Transformer is used to compute the Detrender2 value from the prices that have been smoothed by the 4-bar Weighted Moving Average (WMA). Detrender2 is smoothed in the 4-bar WMA to produce Smooth2. The alpha of the EMA is computed from the computed period, and the EMA of Smooth2 is taken using that alpha and is called the DetrendEMA. The difference between Smooth2 and the
DetrendEMA is multiplied by 1.4 to produce the Predict phasor. Finally, the Smooth2 and Predict phasors are plotted as indicators.
The Optimum Predictor is plotted as the subgraph below the price chart. Buy and sell signals occur when the Predict and Smooth2 lines cross. Based on Dr. Ehlers comments, most of these signals are indeed prescient. The Optimum Predictor could probably work best in trading systems when used in conjunction with other
rules to eliminate the false signals.
Key Signal
Smooth --> 4 bar WMA w/ 1 bar lag
Detrender --> The amplitude response of a minimum-length HT can be improved by adjusting the filter coefficients by
trial and error. HT does not allow DC component at zero frequency for transformation. So, Detrender is used to remove DC component/ trend component.
Q1 --> Quadrature phase signal
I1 --> In-phase signal
Period --> Dominant Cycle in bars
SmoothPeriod --> Period with complex averaging
Predict --> fast line of optimum predictor
Smooth2 --> slow line of optimum predictor
Pros and Cons
100% John F. Ehlers definition translation of original work, even variable names are the same. This help readers who would like to use pine to read his book. If you had read his works, then you will be quite familiar with my code style.

In real life, I am a prolific inventor. I have successfully applied for more than 60 international and regional patents in the past 12 years. But in the past two years or so, I have tried to transfer my creativity to the development of trading strategies. Tradingview is the ideal platform for me. I am selecting and contributing some of the hundreds of scripts to publish in Tradingview community. Welcome everyone to interact with me to discuss these interesting pine scripts.
The scripts posted are categorized into 5 levels according to my efforts or manhours put into these works.
Level 1 : interesting script snippets or distinctive improvement from classic indicators or strategy. Level 1 scripts can usually appear in more complex indicators as a function module or element.
Level 2 : composite indicator/strategy. By selecting or combining several independent or dependent functions or sub indicators in proper way, the composite script exhibits a resonance phenomenon which can filter out noise or fake trading signal to enhance trading confidence level.
Level 3 : comprehensive indicator/strategy. They are simple trading systems based on my strategies. They are commonly containing several or all of entry signal, close signal, stop loss, take profit, re-entry, risk management, and position sizing techniques. Even some interesting fundamental and mass psychological aspects are incorporated.
Level 4 : script snippets or functions that do not disclose source code. Interesting element that can reveal market laws and work as raw material for indicators and strategies. If you find Level 1~2 scripts are helpful, Level 4 is a private version that took me far more efforts to develop.
Level 5 : indicator/strategy that do not disclose source code. private version of Level 3 script with my accumulated script processing skills or a large number of custom functions. I had a private function library built in past two years. Level 5 scripts use many of them to achieve private trading strategy.

72s: Adaptive Hull Moving Average+One challenging issue for beginner traders is to differentiate market conditions, whether or not the current market is giving best possibility to stack profits, as earliest, in shortest time possible, or not.
On intraday, we've seen some big actions by big banks are somewhat can be defined --or circling around-- by HMA 200 . I've been thinking on to make the visuals more conform to price dynamics (separating major movement and minor noise) to get clearer signs of when it starts to happen. So it will be easier to see in a glance when the strength starts really taken place, with less cluttered chart.
This Adaptive HMA is using the new Pine Script's feature which now support Dynamic Length arguments for several Pine functions. ( read: www.tradingview.com). It hasn't support the built-in HMA() directly, but thankfully we can use its wma() formula to construct. (Note: I tweaked a bit HMA formula already popular here by using plain int() instead of round() on its wma's length, since I find it precisely match tradingview's built-in HMA).
You can choose which aspect the Adaptive HMA period will adapt to.
In this study I present it with two options: Volume and Volatility . It will "moves" faster or slower depends on which situation the aspect is currently into. ie: When volume is generally low or volatile readings is not there, price won't move very much, so the adapting MA will slow down by dynamically lengthen the lookback period, and vice versa, and so on.
Colour-markings in the Adaptive resembles which situation explained above. In addition, I also combine it with slope calculation of the MA to help measuring trend-strength or sideway/choppy conditions.
This way when we use it as dynamic support/resistance it will be more visually-reliable.
Secondly, and more important, it might help us traders with better probability info of whether or not a trade should even worth to be made . ie: If in the mean time market won't give much movement, any profit would also only as much. In most cases, we might better save our dime for later or place it somewhere else.
HOW TO USE:
Aside from better dynamic support/resistance and clearer breakout confirmation, MA is coloured as follow:
YELLOW:
Market is in consolidation or flat. Be it sideways, choppy, or in relatively small movements. If it shows up in a trending market, it may be an earlier sign that current trend might about to change its direction, or confirming a price broke-out to another side.
LIGHT GREEN or LIGHT RED:
Tells if a trend is forming but still relatively weak (or getting weaker), as it doesn't have volume or volatility to support.
DARKER GREEN ot DARKER RED:
This is where we can expect some good and strong price movement to ride. If it's strong enough, many times it marks a start of new long-lasting major trend.
SETTINGS:
Charger:
Choose which aspect your HMA should plug itself into, thus it will adapt to it.
Minimum Period, Maximum Period:
172 - 233 is just my own setting to outmatch the static HMA 200 for intraday. I find it --in my style of trading-- best in 15m tf in almost any pair, and 15m to 1H for some stocks. It also works nicely with conventional EMA 200, sometimes as if they somewhat work hand-in-hand in defining where the price should go. But you can, ofcourse, experiment with other ranges, broader or narrower. Especially if you already have an established strategy to follow to. As you might do with:
Consolidation area threshold:
This has to do with slope calculation. The bigger the number means your MA needs bigger degree to define the market is out of flat (yellow) area. This can be useful if needed to lighten up the filter or vice-versa.
Background colouring:
Just another colouring to help highlighting the difference in market conditions.
ALERTS:
There are two alerts:
Volume Break: when volume is breaking up above average, and
Volatility Meter: when the market more likely is about to have its moment of the big wiggling brush.
USAGE:
Very very nice BUY entry to catch big up-movement if:
1. Price is above MA. (It is best when price is also not to far distance from the MA, or you can also use distance oscillator to help out too)
2. HMA's color is in darker green. Means it's on the charging plug with your chosen aspect.
3. RSI is above 50. This is to help as additional confirmation.
Clear SELL entry signal is same as above, just the opposite.
-------------------------------------------------------
Note:
Lower timeframe of course means more noise to be filtered. Depends on the instrument, you might need to tweak the settings a bit till it conform nicely and shows lots of good trades in history. Here's another example on GBPUSD 5m timeframe:
For exit/take-profit point, you can use a second faster period static HMA. Or you can also use RSI. Here's an example:
Don't get me wrong, on few occasions I found it's still best using static MA to spot fakeouts, breakouts, etc, especially ones that's been already use widely. If that's the case or price actions seems suspicious, simply put the same value for minimum and maximum period settings, and there you have the original HMA with extra features.
For developer, check in the code if you need to customise your own charger.
-------------------------------------------------------
That's it. Hopefully this Adaptive HMA+ could at least be a good sidekick to your own strategy, as it does mine. ;)
[blackcat] L1 Stock Volume AnalyzerLevel: 1
Background
The basic volume analysis is that buyers are in control when the price is increased. The purchase volume takes place at the offer price and represents the lowest advertised price at which sellers sell their shares. When someone buys shares at the current asking price, it shows that someone wants the shares and is included in the purchase volume metric.
Function
L1 Stock Volume Analyzer plot colorful volume candles with different meanings: red for red price bars, green for green price bars, yellow for active buying volume, fuchsia for active selling volume, navy for high active buying volume turn over rate, and white for high active selling volume turn over rate.
Key Signal
VOLUME SIGNAL:
activbuying ---> active buying volume
activselling ---> active selling volume
abtor ---> high active buying turn over rate
astor ---> high active selling turn over rate
PRICE SIGNAL:
cd ---> price covergence and divergence
positioning ---> price positioning
callthshots ---> call the shorts price signal
Pros and Cons
Pros:
1. extract volume detailed information to judge price trend together
2. price convergence and divergence help to identify long and short entry points
Cons:
1. price convergence and divergence visually works well only for <= 8H time frame
2. this indicator only works for stock trading pairs
Remarks
In order to put price and volume in a unified scale, this indicator is scaled. This scaling is not suitable for all markets. At present, it has only been optimized in the stock exchange market.

Probability of ATR Index [racer8]Deriving the indicator:
PAI is an indicator I created that tells you the probability of current price moving a specified ATR distance over a specified number of periods into the future. It takes into account 4 variables: the ATR & the standard deviation of price, and the 2 parameters: ATR distance and # bars (time).
The formula is very complex so I will not be able to explain it without confusion arising.
What I can say is that I used integral calculus & the Taylor series to derive a formula that calculates the area under half of the normal distribution function. Thus, the formula was repeated twice in the code to derive the full probability (half + half = whole). If you can read the code, you might be wondering why the formula is so long...
The reason for this is because in Pine Script, the erf function doesn't exist. You see, the formula for normal distribution is: f(x) = (1/sqrt(2pi))*e^(-xx/2), assuming of course that the standard deviation = 1 and mu (mean) = 1. The next step is to take the integral of this formula in order to find the area under f(x). The problem is that I found the integral, F(x), of the normal distribution formula to be equal to F(x) = erf(x/sqrt(2))/2...and the erf function cannot be directly computed into Pinescript.
So I developed a solution...why not estimate the integral function? So that's exactly what I did using a technique involving the Taylor series. The Taylor series is an algebraic function that allows you to create a new function that can estimate the existing function. On a graph, the new function has the same values as the existing one, the only difference is that it uses a differnt formula, in this case, a formula that makes it possible to compute the integral. The disadvantage of using this new formula is that it is super long and if you want it to better represent the original integral over a wider range of x-values, you have to make it longer.
Signal Interpretion:
The hotter the colour, the more likely price will reach your specified distance.
The 2 values of PAI in the bottom window represent probability & average probability of your specifed distance geting hit.
Applications:
Stop loss placement---
This indicator is useful because it gives you an idea of the likelihood that a stop loss at a particular distance away from price (in ATRs) will be hit over a period of time specified. This is helpful in placing stop losses.
Options trading---
PAI can also be used in options trading. For example, you are using a strangle options strategy, and you want to make sure that price stays within the Strangle's profit range. So you only trade when PAI presents a low probability value of moving at a particular distance in ATRs over n periods.
Anyhow, I hope you guys like it. Enjoy! and hit that like button for me :)
[blackcat] L2 Center Band BollingerLevel: 2
Background
Bollinger bands are a type of price envelope developed by John Bollinger , where price envelopes define upper and lower price ranges. Bollinger Bands are envelopes that are represented with a standard deviation above and below a simple moving average of price. Because the spacing of the bands is based on the standard deviation, they adjust for fluctuations in the volatility of the underlying price.
Function
L2 Center Band Bollinger takes advantage of Bollinger band to detect sideways and trends. At the same time, I made an improvement and the center Bollinger line as a fast-slow-line color band. The algorithm of the color center band is composed of price and volume information, which produces gold cross and dead cross for short term long and short entries.
Key Signal
aa10 --> bollinger middle fast line
aa12 --> bollinger middle slow line
up --> upper envelope
dn --> lower envelope
Pros and Cons
Pros:
1. it can easy see the sections of trends or sideways by width of Bollinger band
2. long and short entries are disclosed
Cons:
1. Some noise is still incorporated in trends
2. due to this is un-optimized version, time frame and trading pairs need to be selected
3. Bollinger re-entry signal is not disclosed yet
Remarks
The long and short signal is compatible to @nilux strategy backtest framework for sandardized backtest scheme: Backtest

[blackcat] L1 Stochastic J Price Action OscillatorLevel: 1
Background
The KDJ oscillator display consists of 3 lines (K, D and J - hence the name of the display) and 2 levels. K and D are the same lines you see when using the stochastic oscillator. The J line in turn represents the deviation of the D value from the K value. The convergence of these lines indicates new trading opportunities. Just like the Stochastic Oscillator, oversold and overbought levels correspond to the times when the trend is likely to reverse.
Function
L1 Stochastic J Price Action Oscillator with Long Strength Indicator use stochastic KDJ signal as input source and it combines with price action algorithm to form a brand-new oscillator which have less noise signal with a long signal strength indicator so as to alleviate inherent KDJ saturation issue.
Key Signal
cond --> buy signal condition from KDJ j value deduction
fastline --> fast line of new oscillator
slowline --> slow line of new oscillator
Pros and Cons
Pros:
1. it takes over KDJ's advantages
2. it can greatly reduce KDJ saturation issue
Cons:
1. no short entry signal is derived.
2. only long signal strength indicator is disclosed
Remarks
An improved version of KDJ with less satration observed.

Cost Analysis Calculator [racer8]The Cost Analysis Calculator tells you whether it is ok to trade based on the costs of doing trade. It is a great risk management tool to use to avoid trades that have heavy costs which can negatively affect the chances of profitability. It takes into account commissions & spread cost. Based on your settings, if the cost is too high, the calculator will show you a sign that reads: "Trade cost is high :(". On the otherhand, if costs are low enough to trade, the calculator's sign will say: "Trade cost is low :)" giving you the green light to trade.
The ATR cost parameter defines the maximum amount of trade costs you are willing to take on. It defines the distance (in ATR units) needed to recover trade costs. For example, if the ATR cost parameter is set to 0.20, that means the indicator will only let you trade if costs are below 0.20 ATR. In other words, the price will have to move in the direction of your trade by 0.20 ATR units in order to break-even.
Below are the calculations I used to derive my formula for this indicator...I'm pretty sure these formulas have never been invented before...lol.
Spread cost = absolute value of (#units)*(Bid - Ask)
Total trade cost = commission fee + spread cost
What defines the profit needed to break-even?
Profit = (#units) * (Change in Price needed to profit)
Profit = (#units) * (Distance in ATR)
Profit > Total trade cost
(#units) * (Distance in ATR) > commission fee + spread cost
Distance in ATR > (commission fee + spread cost) / #units
M*ATR > (commission fee + spread cost) / #units
where M represents the ATR cost parameter set at a default value of 0.20 units.
As always, enjoy :D
RSI week/month level on daily Time frame- You can analyse the trend strength on daily time frame by looking of weekly and monthly is greater than 60.
- Divergence code is taken from tradingview's Divergence Indicator code.
#Strategy 1 : BUY ON DIPS
- This will help in identifying bullish zone of the price when RSI on DAILY, WEEKLY and Monthly is >60
-Take a trade when monthly and weekly rsi is >60 but daily RSI is less thaN 40.
Dual Volatility StopThis merges Volatility Stop & its MTF version both published by u/TradingView . Background is colored green or red when both the current timeframe Vstop and higher timeframe Vstop point in same direction. Aim is to take the standard Vstop script which differentiates market from only uptrend/downtrend to uptrend/downtrend/sideways. There is a tradeoff with this, that there is no need for the Vstop to be always in a position which reduces trade time & frees up capital. However this leads to situations where it takes slightly more time to catch on to a trend after a reversal.
Green Background = Buy
Red Background = Sell
No Background = Flat
Derivative Pivot HL Points Hello.
This script aims to take into account mutable variable Pivot Points' periods.
While doing this, it takes the period between 2 signals that I use in the script:
And these periods in my Pivot HL function integrated into len length (Mutable variables) :
The cornerstone of the script is these facts.
Pivot can be optimized by playing with reversal periods.
These pre-formed levels can be used as Supply and Demand levels.
Regards.
Position SizingHello All,
This script can be used for Position Sizing.
After you entered Capital you have, how much you can Risk per Trade, Profit and Stoploss Levels, it calculates Number of Buys/Sells, Position Size and Reward/Risk ratio. you need to choose one of "Long" or "Short" position you will take.
Number of Buys formula = Capital * RiskPerTrade / Loss
Position Size = NumberOfBuys * EntryPrice
Reward / Risk rate = (TargetPrice - EntryPrice) / (EntryPrice - StoplossPrice)
Enjoy!
Band-Pass FilterJust a clean script that can be applied on top of other indicators/sources or you can take the function out of the source and use it in other scripts.
The idea for this was taken from www.pinecoders.com except I am utilizing an EMA instead of SMA. Simply put, we are combining a low-pass filter (moving average) with a high-pass filter (smoothed difference between the source and moving average). The result is a filter/moving average that provides a great combination of minimizing noise while still reacting strongly to price and trend changes.
I like to use this filter in place of other MAs in Pine Scripts to smooth my data. So instead of doing something like sma(stochastic,5) I can easily plug in bp(stochastic,5). It works just fine for your primary moving averages against price as well.
MACD VWAP IndicatorThis indicator uses a combination of the VWAP, EMA 9 and parts of the MACD in order to detect a bullish or bearish trend.
How to trade it:
Set SL either below or above the VWAP line (orange) and TP to 1:1.5 ratio (depending on last few candles, of course).
If EMA200 is close by then place SL either below or above EMA200 (blue) and TP to 1:1.5 ratio
Important:
Best traded in 15M, 30M => Intraday.
Have fun! :)
[R&D] Moving CentroidThis script utilizes this concept. Instead of weighting by volume, it weights by amount of price action on every close price of the rolling window. I assume it can be used as an additional reference point for price mode and price antimode.
it is directly connected with Market (not volume) profile, or TPO charts.
The algorithm:
1) takes a rolling window of, for example, 50 data points of close prices:
2) for each of this closing prices, the algorithm will check how many bars touched this close price.
3) then: sum of datapoints * weights/sum of weights
Since the logic is implemented in pretty non-efficient way, the script sometimes can take time to make calculations. Moreover, it calculates the centroid taking into account only close prices, not every tick. of a given rolling window That's why it's still experimental.
