Hi folks,
I am a newbie of this paltform and start moving some steps.
I am trying to implement a simple - not for me - trading rule that:
- select from Universe only stocks (S&P500) with previous day DollarVolume greater than XX $ and a volatility measure
- Using the selected stocks from Universe, at market open, evaluate first 15 minutes candle and check if it is greater than previous day high and go Long
- Check for open positions if there is a los/profit liquidating position

Now I am trying to understand how "generate the 15minute bar for each stock in the selected universe. I have seen the "consolidation" stuff, but always attached to single stock. My idea is use the callback "EveryDayAfterMarketOpen" to get the 15min candle and there execute the relative buy. From documentation I dont understand how can I get the first 15 minute candle. Can you help me?
Thanks,
Alex
