Hi Guys
I'm new to QC. I would like to automate some of my daytrading setups. I have briefly read all the documentation, but did not see any clear discussions on picking a symbol set before the open.
For example if I want create an algo that would do the following:
1. at 9:20AM pre-market, find symbols (equity) that are over $1 and under $10, where the last price at 9:20AM is > 20% from previous days closing price.
2. volume at 9:20AM must be > 200k
3. Get the highest high between yesterday's close and 9:20AM (pre-market high)
4. After the market opens go long on break of PM high.
How would i go about doing that.
Is there a sample algo already written that does something similar to this?
Thanks for any help.

Since your algorithm creates an universe of symbols that fall under some criteria, you should start developing a Universe Selection algorithm. In the Coarse Universe, we have price and volume information, the ingredients for your selection. However, since you need the previous close, please save it in a dictionary:
private Dictionary<Symbol, decimal> _prevClose; // In Initialize AddUniverse(coarse => { var symbols = (from c in coarse where _prevClose.ContainsKey(c.Symbol) where c.Price > _prevClose[c.Symbol] * 1.2 where c.Price > 1 where c.Price < 10 where c.DollarVolume > 200000 orderby c.DollarVolume descending select c.Symbol).Take(50); foreach (var c in coarse) { if (_prevClose.ContainsKey(c.Symbol) { _prevClose[c.Symbol] = c.Price; } else { _prevClose.Add(c.Symbol, c.Price); } } return symbols; });After this pre-selection is done, you need to make a History Request to fetch the High for each symbols and continue with your trading logic.

Dean Gutierrez , I'm also interested in that pre-market gap analysis, If you dont mind, could you share the code?

Hi, I'd love that code as well. am trying to implement something similar. I have been looking for patterns with a data scientist and wanted to implement some of the strategies. I am looking for gap ups 30% and making a decision on the first three 5 min candles for a trade at 9:45-9:50. Â I wasn't sure how accurate a program like this would be real time since it would have to calculate gap ups. Â I assume that would take time and didn't know if there were limits.
 I'd love to share work.
Thanks!
