Calculated Bars
1440
Number of bars (numeric range)
Controls how many historical bars Atlas Pro loads and runs its calculations over
Leave at the default; only raise it for analysis on an extremely large timeframe
Calculated Bars sets how many historical bars the Atlas Pro script loads and runs its calculations over. The default of 1440 gives the engine enough history to build full context on every supported timeframe while keeping the script fast and responsive.
Leave Calculated Bars at the default
There is almost never a reason to change this setting. The default of 1440 is tuned to balance accuracy and performance, and the engine relies on it. Only raise Calculated Bars if you specifically need to analyze historical data on an extremely large timeframe — and even then, raise it no further than that analysis requires. For normal use, leave it exactly as it is.
Never set Calculated Bars too low
Setting Calculated Bars below the default starves Atlas Pro of the history it needs to function correctly. Without enough bars, the engine cannot build full context, signals and structure become unreliable, and the script can break entirely or fail to load on the chart. If Atlas Pro stops loading after a settings change, restore Calculated Bars to 1440.
