TradeStation Strategy Fill Estimation

Discussion in 'Automated Trading' started by walterjennings, Feb 12, 2009.

  1. Hey guys.

    I'm trying to figure out a way to change how TS fills strategy limit orders on simulation. Right now I'm having issues with the long term performance summary far overestimating actual market performance. Because this divergence between TS performance and actual market performance is so high it makes it difficult to gauge which systems are profitable and how variations effect them.

    Ideally Id like to find a way to place buy limit orders in a strategy at price X and have them only trigger filled if the price touches X-0.01. rather than the current fill estimation which assumes a filled if the price touches X.

    The current code I use to place buy orders is
    "buy vol shares next bar at price limit;"

    Is there a trick or a way built into TS which would provide the functionality I'm looking for?

    Thanks for your time.
     
  2. You ask an excellent question. Order placement in TS strategies is much more difficult than it first appears. Here is an example of what you may write if I understand your question:

    X= Price:
    Y= IdealPrice:
    If X cross below IdealPrice then
    Begin
    buy vol shares next bar at IdealPrice -1 limit;
    End;

    I hope this answers your question.
