Indicators starts calculating only after I add them

[abusestew]

How do I make indicators apply to previous data too when I add them they only start generating after real live data. It doesn't happen on indicators like SMA, ATR and Volumes but on Volumes Profile it starts generating after adding it, not showing me the indicator calculations on previous data. I don't know about you, but it seems pretty useless to use volumes profile like this.

Hello abusestew,

Thank you for your inquiry and for using NinjaTrader!

This would be expected using the standard Volume Profile indicator. It is a real-time only indicator, unless 'Tick Replay' is enabled. I've included this section of our help guide for your reference;

You can enable Tick Replay and the indicator will also plot values based on historical data. Tick Replay is a property that can be optionally enabled on NinjaScript indicators and strategies which will ensure that the market data (bid/ask/last) that went into building a bar is loaded in the exact sequence of market data events.

When Tick Replay is not enabled, the indicator will function only on real-time data, and therefore does not plot any values on historical data. If you change any property, interval, or instrument on a chart with Tick Replay disabled, these indicators will be reloaded and any accumulated real-time data plots will be lost.With Tick Replay enabled, it will plot using historical data.

For information on how to set up tick replay, you can refer to our help guide here:https://ninjatrader.com/support/help...ick_replay.htm
