Get ID for oldest candle on chart

[nk0815]

Hello,

I have an EA that loops back through many candles on the chart. It works so far when putting it on a live chart, but when I run it in the tester, there are only around 100 candles in the past. and it causes a critical error.

Is there a way to identify the oldest candle on the chart, so that I could stop the loop at that candle? Or add something like "if candle exists" to the loop.

I am aware that I can add a delay to the EA, but that does not solve the problem if it ever occurs on a live chart, so the oldest candle ID would be good to know.

@nk0815 Apparently the loop searching for that last candle is having some limitations. Can you please share that part of the project?

Hey, thanks for the reply

This is the part that checks the candles:

I think I need to find a way to stop the loop once it hits the oldest candle on the chart.

@nk0815 You could use this in custom code

CANDLES = WindowBarsPerChart();

CANDLES is a int variable, this will contain all the visible candles so if you zoom in or out it will change.

Thanks a lot, didn't know that one. This would't give me enough candles though. However, I added a condition to only loop back 2000 candles and it works now
