Hi,

What do you mean by: "i dont' know how to add signal line cross histogram to it?"

Can you show this on a chart screenshot?

Not sure about the exact size of library but if you use the newer version library the size might reduce.

You don't need that library to show a popup alert or play a sound alert.

cTrader automate API has the email and sound alert itself under Notifications: cAlgo API Reference - INotifications Interface (ctrader.com)

i make it. thanks for your amazing library.

it is 10 megabyte with source and i couldn't upload in algorithms.
