The logic behind the edge.
SPY Swing Trading pairs two durable market forces — trend-following and mean-reversion — into one adaptive system for the S&P 500 ETF. It first confirms the macro trend in SPY, then waits for price to stretch well beyond its short-term range before entering long or short in the trend direction, closing the trade as price reverts toward its average. Volatility-based position sizing scales exposure to current conditions, and a user-adjustable stop-loss caps risk on every trade. Written in 2016 and live-traded since, with no re-optimization.
- Confirms SPY is in a sustained uptrend or downtrend (the trend filter).
- Enters long or short when price pushes past a volatility-based threshold away from its short-term range.
- Exits as price reverts to its average; a user-adjustable, volatility-based stop caps risk on every trade.
Every strategy in the RelaxedTrader store is back-tested across a minimum of 10 years of historical market data, with estimated commissions and slippage, before a line of code is sold. If it doesn't hold up under rigorous testing, it doesn't make it to the store.
