Questions from Beginners MQL5 MT5 MetaTrader 5 - page 400

Thank you. Can I get the ID of the last chart created by a user or another script that stopped working?

When a new chart is created, no event occurs, so all open charts must be scanned periodically. We have to use:

ChartFirst	Returns chart ID of the first chart of the client terminal
ChartNext	Returns chart ID of the next chart

Got it, thanks.

Another question, how to call iCustom on a new chart previously created using the script?

How do I write a condition to open an RSI order from the 30/70 level ? Will iRSI do? Or will I have to write a function to calculate the indicator value? <br / translate="no">

Leanid Aladzyeu:

Try it :) A lot depends on the strategy as well...

And I understood it this way: you want to attach a custom indicator to the new chart.
