Time Window

The Time Window rule restricts your strategy to only look for entry signals during a specific time range within the trading session. This simple but powerful filter eliminates the most dangerous and unpredictable periods of the trading day.

How Time Window Works

You define a Start Time and End Time. The engine will only evaluate entry conditions between these two times. Outside the window, no new entries are generated — regardless of how perfect the technical setup might be.

Why Use a Time Window?

Avoid the Opening 15 Minutes

The first 15 minutes after market open (09:15–09:30 on NSE) are characterized by:

Gap fills and extreme volatility
Order book chaos from overnight positions
Inflated spreads and slippage

Avoid the Closing Hour

The last hour (14:30–15:30) often sees:

Institutional portfolio rebalancing creating unpredictable whipsaws
Expiry-day manipulation on weekly options
Random volume spikes unrelated to actual market direction

The Trading Edge

By removing the opening 15 minutes of pure volatility and the closing hour of institutional rebalancing, you prevent getting stopped out by random, unpredictable whipsaws. Your strategy only trades during the cleanest, most predictable part of the session.

Common Time Window Configurations

Window	Use Case
09:30 – 14:30	Standard — avoids opening chaos and closing rebalancing
09:20 – 15:15	Aggressive — captures more of the session
09:45 – 14:00	Conservative — only trades during the quietest mid-session period
09:15 – 09:30	Opening-only scalper — specifically targets opening volatility
14:00 – 15:15	Closing-only — targets end-of-day momentum

Configuration Steps

Select “Time Window” as the rule type
Set Start Time — e.g., 09:30
Set End Time — e.g., 14:30

Time Window can be combined with any other rule types. For example:


Require ALL of:
  ├── Time is between 09:30 – 14:30
  ├── RSI(14) > 60
  └── EMA(9) crosses above EMA(21)

The time window acts as a gatekeeper — technical conditions are only evaluated during the allowed hours.
