I can´t figure out how to compare stocks in a session.
e.g. I don´t want to buy stocks where ADX is above 25, but buy the 10 stocks with highest ADX readings among a 500 stock portfolio.

Is this possible?

Yes it is possible. You need to use the

Market Valuable from the system

 MarketVar("ADXval") = ADX(10, 0)

and then access them from the tradeplan.

ADXval =TradePlan.Session(0).Market(M) .MarketVar("ADXval")

You can then call the CustomRanking functions from the tradeplan.

Look at the StockCustomPerformPlan for ideas of the code.

 

 

 

Where can I find the StockCustomPerformPlan?

In the editor select TradePlans and look on the list for it. It is one of the free scripts that ship with the product.
