Vela Superada Strategy

The Vela Superada strategy trades a two-candle reversal pattern. A bullish setup occurs when a bearish candle is immediately followed by a bullish candle that closes above the prior open. Trades are filtered with a short-term EMA, RSI and MACD trend to avoid counter-trend signals. Both long and short sides can be enabled.

The strategy employs percentage-based take profit and stop loss levels and dynamically tightens a trailing stop once price moves favorably. This allows capturing extended moves while protecting against reversals.
