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.

Frame the question

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

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

Backtest header controls

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.

Metal, venue, candle, range, and capital stamp onto a ticket before the Strategy Builder opens.

What you will see4 steps

A blank Backtest screen appears.

Metal, venue, candle, range, and capital stamp in order.

Chapter 01

Chapter 02

Choose the metal before indicators

Which instrument is actually giving me evidence?

Gold, silver, platinum, and palladium are not interchangeable witnesses. A rule tested on one metal should not be treated as evidence for all metals without a separate check.

Metal selector: GOLD, SILVER, PLATINUM, PALLADIUM

Do not transfer one metal's result blindly.
Use cross-metal checks as later validation.
Keep the first lesson focused on one instrument.

Chapter 03

Respect the active data lane

Am I testing the market lane that is actually enabled?

The current visual Backtest path is COMEX/USD daily OHLC. local market/local currency and weekly/monthly visual candles are visible as unavailable surfaces, so the lesson should not let learners imagine they tested them.

Venue and candle selectors

Use COMEX/USD as the active visual venue.
Use daily OHLC as the active candle set.
Do not claim local market/local currency or weekly/monthly evidence from this flow.

Chapter 04

Choose the date window before return

How much history is allowed to vote on this idea?

The range selector is an evidence-quality control. 1M can show recent behavior, 3Y can give a stronger baseline, MAX can broaden context, and custom windows need a written reason.

1M, 6M, 1Y, 3Y, MAX, and custom range controls

Use short windows for recent behavior, not final confidence.
Compare against wider windows before saving a rule.
Write the reason for custom dates.

Chapter 05

Treat capital as a simulation frame

What does initial capital change, and what does it not change?

Starting capital affects the simulated account display and P/L scale. It does not make a weak rule stronger, and it does not turn the result into a live account projection.

Initial capital input

Use a realistic capital assumption.
Do not read simulated P/L as a live promise.
Keep capital separate from rule validity.
