What this settles — and the next dig

It lagged buy & hold over this window — that's a result, and a backtest you can kill for free just did its job. Re-tuning this same idea until it looks better only adds another shot at looking good by luck, so the honest next move is a fresh one: test a different strategy on Dow Jones ETF (DIA), or build your own — free. Most ideas die cheaply right here, and that's exactly how the rare one that holds up gets found.

Or stop here — walking away from an idea that didn't beat simply holding is a result, not a failure.

Worked example

Two real trades from this backtest

Shown at the modeled fills — entries at the next open; a stop at its level, or at that day's open if the day opened past it; a target at its 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.

52 trades total — 19 winners, 33 losers (37% 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.

  1. Entry. A long entry fired; filled at the next open on 2024-10-14 at $428.32 — never the signal bar's own close.
  2. Held. 8 daily bars.
  3. Exit. Exited on 2024-10-24 at $424.32 (the exit rule fired (filled at the next open)).
  4. Result. -1.03% after costs.

The worst single trade in this whole test reached -6.81%.

  1. Entry. A long entry fired; filled at the next open on 2024-06-21 at $391.67 — never the signal bar's own close.
  2. Held. 23 daily bars.
  3. Exit. Exited on 2024-07-25 at $398.63 (the exit rule fired (filled at the next open)).
  4. Result. +1.68% after costs.

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.

How to read this
  • • The strategy line is MACD on Dow Jones ETF (DIA); the dashed line is simply buying and holding DIA. 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.
What this is — and isn't

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. We 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.
