A Backtest Without Spread and Swap Is a Novel

A Backtest Without Spread and Swap Is a Novel. The honest one-sentence object of this lesson is FX tests that include spread, swap, Sunday gaps. If you cannot say that without opening a platform, you will size the wrong clock. The failure mode that actually hurts accounts is testing mid prices with zero cost. Write the object, then size. Educational only.

Analog, not identity: costs are the first filter. This page is not a lesson in crypto pairs or listed index futures. Different machine, different hours, different ruin path. Contrast the object with futures hub rather than treating every product as the same machine.

1. Spread

Spread is the first working definition. FX tests that include spread, swap, Sunday gaps. People skip this because a chart is easier than a specification. A chart is not a spec. If you cannot explain Backtesting FX: Spread, Swap, Sunday Gaps to a skeptical friend without a screenshot, you do not understand it yet.

Keep a crib note: object, invalidation, dollar cap. Testing mid prices with zero cost is how cribs get skipped. Do not skip. For the arithmetic habit, use stop calculator until dollars are boring.

2. Swap

Swap. Convert every pretty statement into dollars. The arithmetic below is illustration — live ticks, pips, and margins change. Re-read the live schedule.

If round-turn cost is 1.4 pips and edge is 1.1, $219 stays paper. The test failed.

If that arithmetic already exceeds your cap, the lesson is over: pass or step down in size. Passing is a position. Confirm the dollar translation with margin calculator so the notebook and the statement agree.

3. Sunday gaps

Sunday gaps. Context is not a trigger. Costs are the first filter. Use context to veto, not to force a click.

When in doubt, name FX tests that include spread, swap, Sunday gaps again. If the sentence changed, you changed trades without admitting it. Related structure: free calculators.

4. Overfit

Overfit. Process beats mood. Write the rule that fires without a debate at the worst moment. If the rule is 'I'll see how I feel,' you do not have a rule.

Stops, flatten policies, and session boundaries belong in the same notebook as the thesis for Backtesting FX: Spread, Swap, Sunday Gaps. If the stop is a price, convert it with listed venues after you already know the tick or pip.

5. When not to automate

When not to automate. Limits: this page will age; specs, leverage caps, and dealer rules move. The live document wins. Educational only. Not NFA, tax, or a solicitation.

Re-read primary docs before you add size on the object of Backtesting FX: Spread, Swap, Sunday Gaps. See also previous lesson when the confusion is the venue layer, not the chart.

6. Mistakes, limits, takeaways

Mistakes: testing mid prices with zero cost; copying size from a stream; ignoring costs; mixing this machine with crypto pairs or listed index futures. Another: treating Backtesting FX: Spread, Swap, Sunday Gaps as advanced because the vocabulary is long rather than because the dollar cap is written. If the sister asset class is the real mix-up, next lesson before you add size.

Maps go stale. Costs are the first filter. If this lesson and the live spec or statement disagree, the live document wins.
