Does these data provider also provide open interest data in data feed?
No, Indian MT4 data feed don't have such details. There are many may be some start that. Till few month ago most providing only LTP (even no bid ask).
Even u can't always trust volumes (I think it is in ratio mostly correct).
But when LTP is correct and updating is very fast, most price based indicators worked well.
If u r using vwap type volume based indicators u need to test demo first...
Out of this volumes is more correct with finmas.. But not sure they have bank nifty weekly options or not. Used them b4, then it was not there. There was monthly options only.
Now with using tradize MT4 server.
It added bid-ask chart for MCX, NCDEX and Nifty only. Still waiting for BNF bid-ask. bnf weekly options is there.
If someone is using mainly price based indicators.. MT4 is very good..
When many brokers make the restriction on market watch scripts.
U can load side by side 100 charts in MT4. Yes 100 is the limit. :thumb:
That is one of the main reason I used it, all 100 charts working side by side, with consuming lowest bandwidth...U can set pop-up alert sound alert on particular chart with particular tf too.
