I have been a subscriber of Market data Provider for nearly a year and find that their realtime intraday data is not consistent. Here are the issues:
- Data does not start updating at exact time market opens. The opening bar/candle formation is different when compare to other service providers.
- So called tick based data appears to be sampled at a low frequency, giving less accurate candle formations. For example a price upmove which happens in two bars can end up being shown as just one bar in MDP. This is really a problem when you are trading intraday and want an entry in a rapidly moving market.
- Data updation stops inexplicably and their support team needs to be informed about such an occurence. They do not detect or fix it automatically. Have lost 20-45 minutes of trading time 2-3 times a month.
- Backfill data can change your candle formations as it is different from their realtime data. This plays havoc with your historical data as you see the cumulative calculations of profit going haywire.
- You can do only one backfill every 2 minutes as they seem to have imposed this restriction recently.
- Their support is only via chat. This is a major issue. You cannot have any serious discussion with anyone senior from their team about operational issues.
Its a pity, their updation software is amongst the lightest available, but when the data is not complete, I wouldnt recommend them for the serious trader.
