I'm writing an EA that generates a HST in real time. This HST is displayed in a Offline Chart window.
When the EA generates a new bar, I'd like to display it to the Chart.
So I need to refresh that chart with the new data. Each existing script (based on PeriodConverted) I've read use PostMessageA(). But PostMessageA sends a Windows DLL call.
Since such calls are prohibited by mql5.com Market, how can I update the chart without making a Windows DLL call?
