Backtest: Set The Test Context Before Rules

A practical Backtest lesson for setting the test ticket first: instrument, enabled market lane, sample window, and capital assumption before any strategy logic is allowed to matter.

Chapter 01

Build the context ticket first

Trader question

Which market, venue, candle, date window, and capital assumption am I testing?

The test context decides what the result can mean. Before the Strategy Builder opens, the learner should be able to name the metal, active venue, candle set, sample range, and capital frame.

Desk checklist

Choose the instrument intentionally.
Confirm the enabled venue and candle lane.
Write down the date window and capital assumption.

Interactive proof

Use the Test Context Console to change metal, range, and capital before any rules are written.

1MetalGold, silver, platinum, and palladium can each tell a different story.Choose the instrument before choosing indicators. A rule that survives gold still needs a separate check elsewhere.

2Venue and candleThe current visual path is COMEX/USD on daily OHLC.local market/local currency and weekly/monthly visual candles should be treated as unavailable until the tool enables them.

3Date window1M, 6M, 1Y, 3Y, MAX, and custom windows change the evidence quality.Short windows can be useful for stress, but they are not enough to trust a rule alone.

4CapitalInitial capital changes the simulated account frame.It is an assumption for the backtest display, not a promise about live account outcomes.

The context ticket is the first risk control. If market, candle, date range, or capital changes, the backtest is a different case.
