I switched from Qcharts to Esignal and now i'm in hell. Esignal is so fast and is never delayed... BUT THE STUFF THEY CALL DATA IS CRAP.
They deliver you shit in a nanosecond. Now i'm not here to slander Esignal but they are having major problems. There tick servers have bad ticks... if you know what that is, you know what it can do to a chart.... and to top it off, you can't choose what server you want... so some are good and some are bad. To top it off, you don't know when you are getting bad ticks, unless you constantly compare one data service to another.
If you don't know what bad ticks can do to a chart... it's not the price thats messed up, it's how the bars are drawn. Compare the bars of the different charts... they are all different!!!!!
I'm not saying qcharts is great or anything, and thats why i switched... they are slow, and they are slow, and they are slow..
but at least when the data gets there, it's good data. And if a tick server is messed up on qcharts... you can manually route to another server.
If you know of a reliable data provider, and I mean reliable as in fast and accurate... pls share it with me.
