Hi,
(1) I assume you were not talking about my TPO profiles code, because on the contrary it was designed to make sure it works on IG too inside price chart and with customisable session times as subset of 24h-cfd dataflow. However, in case my assumption was wrong and you’re one of the new current free trial takers, then for forum housekeeping please use the “get support” messaging system or store email or dedicated store forum topic instead, thanks.
(2) I also assume you were not just asking about the more general item “how to place an indicator on chart”, but in case I’m wrong again and you were asking about this:
https://www.prorealcode.com/blog/video-tutorials/how-to-add-an-indicator-on-price-prorealtime/
(3) So, last choice, I assume you were talking about this optional PRT module:
(English) https://www.prorealtime.com/en/market-profile-pop
(Italian) https://www.prorealtime.com/it/market-profile-pop
then, it is a paid-for option at 33€/month before tax (around 40€ tax included) which to the best of my knowledge should include a recurring fee to the CBOT (Chicago Board of Trade), the R surrounded in above links next to “market profile” meaning it’s registered in the U.S. Patent and Trademark Office.
It is available in “PRT software” offer, or PRT with some brokers only, but IG is not one of them unfortunately, which probably answers the main part of your question. I can only guess (and I insist this is just a guess, not a fact) they didn’t find commercially interesting to propose it if they couldn’t provide it for free. So, sorry, but unable to answer factually for them as to the “why” part of the question.
Best wishes
