Hello,

I am using BasicSymbolData.AccumulatedLastTradeVolume in an ACSIL custom study and it works well in real time.
However, I would like to perform a backtest with this study. With BasicSymbolData.AccumulatedLastTradeVolume I always get the current value and not that of the replay.

Is there a way to get something like BasicSymbolData.AccumulatedLastTradeVolume for the current time point in the replay?

Thank you!

That volume value is definitely updated during a replay. So not sure why you would have any issue with this.

Thank you for your quick respond.

I use a Chartbook with two orderbooks who are identically. On both is a custom study added, which adds a message to the Message Log containing the LTQ, given by BasicSymbolData.AccumulatedLastTradeVolume.

When I replay one Orderbook while the other is not replayed, I allways get the same LTQ for both orderbooks. The LTQ displayed in the replayed orderbook seem to be correct. How can I access this value with ACSIL?

The output is:
