How to Trade Using the Automatic Trendlines Indicator
Traders can use the automatically drawn trendlines to implement strategies based on trendline breakouts and trendline failures (bounces).
Trendline Breakout Trading
A breakout signals strong momentum and indicates the price may continue moving beyond support or resistance.
If a downtrend line breaks, traders may consider a sell position with stop loss above the previous high.
If an uptrend line breaks, traders may consider a buy position with stop loss below the previous low.
Trendline Failure (Bounce Trading)
When price fails to break a trendline, it suggests weakening momentum and a potential reversal.
If price fails to break a downtrend line, traders may consider a buy position with stop loss below the trendline.
If price fails to break an uptrend line, traders may consider a sell position with stop loss above the previous high.
Learning and Strategy Development
