Volume calculation when importing historical data

[tolisss]

Hi

I need some help to understand how to calculate the volume required from ATI Last function.

Let's say I have a 2 trades for a given interval (1min), one trade is short with volume 10 and price 1 and the other is long with volume 21 and price 3. To my understanding I should pass 21-10 = 9 for volume and 3 for price as arguments in the Last method?

Hello tolisss,

The Last() method sends a last tick of incoming data into NinjaTrader if you would like to create your own custom data feed.

The volume would be the volume of that tick. I'm not sure how to relate this to your inquiry about open positions..
