Overview
Trend #4 - ATR+EMA channel generates long entries when price crosses above the blue channel and red EMA with zero position, using position sizing based on stoploss divided by the gap to the stop level. Short entries mirror this logic when price breaks below. Entries use a limit at the opposite ATR band and a stop at the red EMA. The strategy offers non-breakout and breakout modes. Main inputs control channel lengths, ATR multiplier, and entry filters. The script draws directly on the price chart.

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
