Day of Week

Time · Window

Boolean signal — true on bars whose weekday is enabled. Defaults to Monday–Friday (forex / stock convention; weekend data is rare anyway, but crypto bars include it).

Day of Week emits true only on bars whose weekday is one you've enabled. It lets you trade — or skip — specific days. Markets have day-of-week personalities: Mondays can gap and chop as the week finds direction, Fridays often see position-squaring into the weekend, and crypto trades right through Saturday and Sunday while forex and stocks don't. This block turns those patterns into a simple filter.

How it works

Seven toggles — Mon through Sun — let you switch each weekday on or off; the block outputs true on bars whose day is enabled. It defaults to Monday–Friday on, weekend off, matching the forex/stock convention (and weekend forex/stock data is rare anyway). For crypto, whose bars include Saturday and Sunday, you can enable the weekend or deliberately exclude it. The Bars input aligns the signal; And the On day output with your entry logic.

When to use it

Use Day of Week to exclude or isolate weekdays that don't suit your strategy. Common cases: skipping Mondays if your system struggles with early-week noise, avoiding Friday afternoons before the weekend, or — for a crypto strategy — choosing whether to trade the typically thinner weekend sessions. As with hour-slicing, be disciplined: dropping a weekday purely because it looked bad on past data is curve-fitting unless there's a real, persistent reason.

Example

Skip Mondays: wire Bars into Day of Week with Mon off and Tue–Fri on, then And the On day output with your entry into a Buy Signal. Backtest with and without the Monday exclusion in the Tester to judge whether it's a real effect.

Tips & gotchas

• Defaults to Mon–Fri — weekend off, the forex/stock convention.
• Crypto includes weekends — decide deliberately whether to trade Sat/Sun.
• And it with entries — a gate, not a trigger.
• Don't curve-fit weekdays — exclude a day only with a real reason, and validate out-of-sample.
