I'm looking for something like an RTD feed for excel that can give me the most recent OHLC bar data for whatever timeframe I specify such as 15 min, 90 min, daily. This is for futures products. Doesn't matter if its free or paid, just looking for a reliable feed.
My plan is to take the most recent OHLC data for those timeframes I specified and paste it to the next available row using a vba macro i wrote so I can build up the intraday bar chart history. I already have coded this part out but ideally if the datafeed supplier has some kind of settings that can do that automatically than all the better since my code might break down.
This is for a live trading system so I am not looking for something that can just pull up the last 100 bars historical data, as that won't work for me.
Does anyone know any reliable suppliers/systems to build something like this? Thanks
