ZEMA Crossover Strategy with Volume & ATR Filters

This strategy is based on the crossover of two ZEMAs (Zero-Lag Exponential Moving Averages) with additional filters for volume and ATR to confirm signals. It automatically opens long ("Long") and short ("Short") positions and sets stop-loss and take-profit levels based on ATR.

Long Position ("Long"): Opens when ZEMA1 crosses above ZEMA2, volume exceeds the threshold (if filter is enabled), and ATR is above its SMA (if filter is enabled).
Short Position ("Short"): Opens when ZEMA1 crosses below ZEMA2, with the same filter conditions.
Stop-Loss and Take-Profit: Automatically set based on the current ATR value. For example, with a multiplier of 2.0, the stop-loss is 2×ATR from the entry price.
ZEMA lines are plotted on the chart: green (ZEMA1) and red (ZEMA2). The area between them is filled with color (green for bullish, red for bearish).
