Does the Fair Value Gap strategy beat buy & hold on Energy Sector ETF (XLE)? (XLE · backtested honestly)
A three-candle price imbalance — a gap between the first candle's high and the third candle's low, confirmed at the third candle's close — that price may later return to before continuing higher or filling back in.
Over this period, Fair Value Gap on Energy Sector ETF (XLE) returned +17.0%, while simply buying and holding returned +181.3% — it lagged buy & hold by 164 points, with a worst drawdown of -23.6%. It traded 54 times and sat in cash about 70% of the time. It's a mechanism you test — not a recommendation.
It lagged buy & hold over this window. That's a result — a backtest you can kill for free just did its job, and re-tuning it until it looks better only adds another shot at looking good by luck. Walking away from an idea that didn't beat simply holding is the honest move, not a failure.
If you still want to try to break it further, the five stages show how — but the cheapest lesson is the one you already have.

Shown at the modeled fills — entries at the next open, protective stops and targets at their level; costs on. A single trade is never a signal and says nothing about the next one — not the best or worst, a middling winner and a middling loser among the completed trades.
54 trades total — 26 winners, 28 losers (48% won). Below is one of each, not a scoreboard. One position is still open at the window end — its result is unrealized and is counted in the totals above at its current mark, not shown as a card below.

Trading costs + slippage (0.10%) are already deducted from every figure above. One trade is never the edge — it's the whole distribution (the win rate, the losers, the reality-check) that matters; this just makes the mechanics concrete. It describes the past; it is not a prediction.

Beating the dashed line is the whole point — many strategies don't.
- • Max drawdown is the worst peak-to-trough fall you'd have sat through. A higher return with a much deeper drawdown is not obviously better.
- • Every fill assumes next-open execution with costs & slippage on — no acting on prices you couldn't have known.
- • A small number of trades means a small sample. Treat a great-looking result on a handful of trades with suspicion.
This is a hypothetical backtest of a well-known mechanism on past data. It is not advice, not a prediction, and not a claim that the strategy works. I hold no funds and place no orders. The value here is the ability to test an idea honestly — see where it would have helped, and where it would have hurt — before you ever risk real money on your own broker.
