very, very good idea, IMO 
i donât understand - if youâre trading with (actually âagainstâ!) 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 elseâs???
what youâre proposing to do sounds terribly difficult and complicated to me, and unnecessarily so
why? why not do your analysis on CTrader, if thatâs what youâre trading from? otherwise youâll be analyzing a different instrument from the one youâre trading?
regarding IC Markets: they are a âtricksyâ 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 donât 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 âbrokerâ is where and by whom your account is regulated
