Accessing Buys / Sells volume in the default indicator BuySellVolume

[cincai]

Can i know how to access Buys / Sells volume in the default indicator BuySellVolume.

The value i get is always Zero, I use market replay to test it.
Can i know why ??

But when i Used the default BuySellVolume, it did actually have the value to plot out the line.

Below is my indicator that access Buys from BuySellVolume indicator.

Hello cincai,

This is a realtime only indicator which would need OnEachTick.

To access the data in realtime you could do that by just calling the indicator, your parent indicator also needs to be OnEachTick:
Print(BuySellVolume().Sells[0]);

Because of how the indicator sets the plot data it may work more in your benefit to just extract the code used and then re use that code in your script.

I look forward to being of further assistance.

Hello cincai,

Right, I had mentioned that. If you wanted to use this in also for historical it would be best to just include that type of logic in your script instead of trying to access the plot data through the indicator. The indicator uses OnMarketData to calculate the volume, while that would work with tick replay enabled it would still produce 0's in historical if called from another script. Including this logic in your script directly would be the way around that but would still require using TickRelay for OnMarketData to be called historically.


I look forward to being of further assistance.
