I have been using IQFeed for a while and looking for something better.
Just 1 minute data, I don't need ticks. 10 years or more.
I mainly trade forex, some futures. With equities I am content with daily data. For futures I need continuous contracts too.
But it needs to be accurate It can't have big differences between close of one minute and open of the next at random times (unrelated to market activity). That makes serious data analysis, backtest and optimization very difficult.
I don't expect anything for free. Or dirt cheap. But I'm not an institution.
Needs to be accurate! did I say that already? Sorry for being frustrated.
