Discussion of article "Creating Tick Indicators in MQL5" - page 3

 

Good afternoon!

Thanks for the article and the codes. Can you please tell me why it works like this?

I take your tick chart, compile it without changes and paste it to EURUSD M1. A window opens at the bottom, the ask and bid values change in white (in the upper left corner), but the chart at the bottom of the red and blue bars does not appear.

Then I move the chart to the left, enough so that I can't see the current candle at the top and the charts at the bottom appear. I move it back to the right - the current candle is visible at the top, but there are no charts at the bottom.

 
Saw a link to the corrected indicator above. Downloaded it, thanks, everything works )

MT4 does not store historical tick data. You would have to store the tick data yourself. Search the CodeBase as there should be several MT4 versions for Tick Charts.

how does the indicator downloads  previous bid and ask price if it only uses symbolinfodouble
