Bollinger Bands Performance - TradingED
Key components of the original indicator:
• The Bollinger Bands are a technical analysis tool developed by John Bollinger to generate signals of overbuying and overselling.
• There are three lines that compose Bollinger Bands: one Simple Moving Average (middle band) and an upper and lower band.
• The Upper and Lower Bands are typically used with 2 Standard Deviations +/- of a 20-day Simple Moving Average (or 20 candles) but can be modified.
The use of Bollinger Bands is based on the concept of mean price reversal, assuming that if the price deviates from the Moving Average it will eventually return to the mean price. As recognized by its creator: John Bollinger , "the touches of the bands are just that, touches, not signals".
So, a touch from the top is not in itself a sell signal and vice versa, a touch below should not be a buy signal either. A trader must look at the general direction of the price and then only take signals that align with the trend. For example, if the trend is down, you should only consider short positions when the lower band is indicated, and in case of an uptrend, take only long positions.
Another important point in the use of this indicator is that the bands will expand and contract as the Price Action becomes volatile (expansion) or is limited in its trading pattern (contraction). After a strong rise or fall in the trend, the market may consolidate, trading closely and crossing over and below the Moving Average until defining a new course, or continuing with the previous direction.
Main functions of this modified indicator:
1) You can select the type of MOVING AVERAGE, among many available options ( SMA , EMA , DEMA , HMA , etc.)
2) The SOURCE for the count can be determined by the trader (close, open, etc).
3) The MEASURE can be based on a CANDLES count if you are trading OHLC Charts from 1D onwards, or if your trading is intraday, you can also select counts by MINUTES, HOURS or DAYS, depending on your trading style.
4) LENGTH, by default it will be loaded as 20 but considering the previous point, you can modify it according to your convenience.
5) STANDARD DEVIATION, by default it will come loaded with 2 deviations, but you can modify it according to your convenience to operate.
