This is addressed to the original poster (“several”) and also to the developers of PRTv12.
You are correct, several. But it’s not only other apps that can handle zooming out on a chart without this loss of OHLC information: there was no problem whatsoever in PRTv10.3.
The developers either do not understand what they are doing or, if they do, they are motivated by a desire to make life more difficult for their trading customers and, by restricting the trader’s access to information in this way, easier for the brokers to take advantage of them.
I’m really surprised that traders who use PRT are not up in arms about this.
