This strategy uses the weekly 20-period SMA and 21-period EMA to determine buy and sell signals. It buys when the EMA crosses above the SMA and sells (or closes the position) when the EMA crosses below the SMA. The strategy uses 100% of available equity for trades, includes a 10% equity stop-loss, and accounts for a commission of 0.1% and slippage of 3 ticks. It is designed to match weekly calculations on a daily timeframe without peeking ahead at future data.
