very, very good idea, IMO
i don’t understand - if you’re trading with (actually “against”!) IC markets, surely you should use their data-feed? your bets are on the prices of their products, so you need to make your decisions based on charting their prices, surely, not anyone else’s???
what you’re proposing to do sounds terribly difficult and complicated to me, and unnecessarily so
why? why not do your analysis on CTrader, if that’s what you’re trading from? otherwise you’ll be analyzing a different instrument from the one you’re trading?
regarding IC Markets: they are a “tricksy” brokerage who run multiple different companies and most of the accounts people open with them are not properly regulated (they claim on their website to be regulated by ASIC but if you don’t live in Australia yourself and open an account with them, your account will probably not be ASIC-regulated, and that matters very much!)
the issue that eclipses everything else in importance, before you send money to a counterparty market-maker “broker” is where and by whom your account is regulated
