Scaling_mastery:Free TrendlinesScaling_mastery Trendlines is a clean, trading-ready smart trendline tool built for the Scaling_mastery community.
It automatically finds swing highs/lows and draws dynamic trendlines or channels that stay locked to price, on any symbol and any timeframe.
🔧 Modes
Trendline type
Wicks – classic trendlines anchored on candle wicks (high/low).
Bodies – trendlines anchored on candle bodies (open/close), great for closing structure.
Channel – 3-line channel:
outer lines form a band around price
middle line runs through the centre of the channel
thickness is adjustable (Small / Medium / Large).
Trend strength
Controls how strong the pivots must be to form a line.
Weak → more lines, reacts faster.
Medium → balanced, good for most pairs.
Strong → only the cleanest swings, higher-probability trendlines.
🎨 Visual controls
Max support / resistance lines – cap how many lines are kept on chart.
Show broken lines – hide broken trendlines or keep them for structure history.
Extend lines – None / Right / Both.
Support / Resistance colors – separate colors for active vs broken.
Channel thickness – Small / Medium / Large (0.5% / 1% / 2% of price).
Channel outer lines – color for channel edges.
Channel middle line – color + style (dotted / dashed / solid).
Broken lines are automatically faded + dotted, so you can instantly see what’s still respected and what’s already been taken out.
🧠 How to use
Add the indicator to any chart.
Start with:
Trendline type: Wicks
Trend strength: Strong
Max lines: 1–2 for both support & resistance
Once you like the behavior, experiment with:
Switching between Wicks / Bodies / Channel
Adjusting Channel thickness and Trend strength
Use the lines as a visual confluence tool with your own strategy:
HTF trend direction
LTF entries / retests
Liquidity grabs around broken lines
This script doesn’t generate entries or risk management – it’s designed to give you clean, reliable structure so you can execute your own edge.

TrendLine ChannelsAbstract
This script provides a set of Trendline Channels which can be tighter than Donchian Channels.
This script computes the most suitable active upper and lower trendlines and updates them as soon as possible.
We can use it for breakout signals earlier than Donchian Channels.
Introduction
Channels are tools which can mark area of values of ranging markets.
Once the price leaves the original region, range traders may start admitting they are wrong and trigger trend.
Donchian Channels (misheard as Dungeon Channels) use the highest and the lowest price to define area of values.
When the price breakouts, it just like it got released from a dungeon.
However, waiting for the price making even higher or lower may be too late and risk reward ratio may be lower.
Trendlines can make the channels tighter and we can find earlier breakout signals.
Computing Trendline Channels
(1) Find the most active trendlines
In this script, a valid trendline connects two high values or two low values.
A high value means the highest value in a trading day.
A low value means the lowest value in a trading day.
In this script, every trendline does not crossover any bar but can exactly touch them.
The most flat trendline is taken. (one for upper and one for lower)
(2) Continue to use or Change a trendline
If there is a tighter trendline available, this script changes to use it.
If the previous active trendline is broken, this script re-computes the trendline available.
When this case happens, this script display with an another color.
Otherwise, this script continues using the previous trendline.
(3) Middle line
The middle line indicates the middle value between the upper and the lower.
Parameters
Length : how many days are used for computation. The default value is 16 just because 16=4*4, using binary characteristic.
x_go_on : If the previous trendline is not breakout and there are no tighter trendlines available, we continue use it.
Color Options
(1) Upper trendline (no update or tighter)
(2) Upper trendline (changed due to breakout)
(3) Middle line
(4) Lower trendline (no update or tighter)
(5) Lower trendline (changed due to breakout)
Conclusion
Trendline Channels can be tighter than Donchian Channels and evaluate earlier breakout signals.
Comparing to known auto trendline scripts, Trendline Channels is continuous.
Once a trendline is broken, Trendline Channels can instantly point out the next available one.
If you think the price movement is boring or you cannot have good risk reward ratio, you can go to an another timeframe.
