Anyway, most of the brokers have drifted away from RTD. Some are giving data feed thru websocket. Websocket seems to be more efficient than RTD . So I may not give much support for RTD hereafter.
have developed an application for myself that gets data feed from Finvasia Websocket to Amibroker. Quality of data feed is good and backfill is superfast. It is still in testing phase.
