Hi, Bookmap Team and users,

I want to write a custom indicator that calculates volume delta study on multiple symbols combined. Is it possible?

I know there is a correlation tracker function, so it's possible to reference data from another symbol, what if I want to reference more than one symbol at once?

Hi shixin121,
Take a look at simplified demo in Demo Strategies project and MultiInstrumentListener interface.
