Studies - TraderOS Docs

A study measures how often something happened in the past and what followed. Ask in words, name the market and the window, and the Agent runs it on stored history and shows the sample size.

Studies you can run

Study	The question it answers
Opening range breakout	How often does the first range break, which side first, and how far does it run?
Initial balance breakout	The same for the first hour’s range.
Overnight range breakout	Does price leave the overnight range at the open, and what follows?
Gap fill	How often does a gap fill, and how long does it take?
ATR	How far does this market typically move in a day or a session?
Fair value gaps	How do gaps between candles behave once formed?
Prior day and prior days’ range	What happens at, inside and beyond yesterday’s or the last few days’ high and low?
Prior weeks’ range	The same on weekly ranges.
High and low of the day	At what time of day are highs and lows usually set?
Outside days	What follows a day that takes out both sides of the day before?
Red and green days	How do runs of up and down days continue or reverse?
Session correlation	How does one session (Asia, London) relate to the next?
SMT divergence	When two correlated indices disagree at a high or low, what follows?
Event study	How does price behave around a scheduled event such as CPI or an earnings date?
Similar setups	Find past days that look like today and show how they ended.

Read a study properly

Look at the sample size first. A pattern seen eleven times is not a pattern.
Look at the spread, not just the average: the typical move against you matters as much as the typical move for you.
Ask for a different window to see whether it holds outside the stretch you looked at.
Turn a study into a rule with backtest this. See Backtests.
