  Hello everyone,

  I’m trying a simple autotrading strategy with PRT Bands, just to test it (I’m using IB), but I don’t understand why it works correctly in backtest but not in DEMO. In Demo it doesn’t open positions, anyone can help me why, please? I’ve got a strategy on gold that works, now I’m testing the strategy on large stocks (Tesla and Nvidia) , but for some reason it doesn work. I’m thinking if the problem is the fact it buys at market and not with limit order?

  thank’s anyone in advance who can help me.

  I want to specify that the working strategy on gold is not the same.

  I think you showed the wrong code because it shows with Market Orders ?

  With Demo you mean the PaperTrading option at startup ?

  Might be a margin requirement? 10 shares of large stocks could be too much for your account size/margin

  Yes I mean paper trading. ISn’t correct to use Market order in DEMO? I saw it works for gold (but it’s another strategy). by the way my doubt was another one. Since that during pre market and after market you can enter long only with limit order, is it correct to use “Buy at Market” ? I don’t think that is the problem because I verified that the condition to enter was activeted during regular hours.

  Hi Nicolas,

  my DEMO account has 25K.  10 shares of a stock whose value is 150 $, I don’t believe that could be a problem. COuld be because IB does work only in a limited choiches so far?

  What kind of time frame do you use for this code?

  I don’t know how long you ran this code in demo but it may take a while for a position to open…

  strategy was lunched on 4th of march, in attachment you see the chart of the strategy where there are no positions open, on the right chart the backtest. As you can see a position should be opened but there is nothing. I cannot explain. someone can understand why?

  Are you using the same value for Spread in the Backtest as will be used during Live running?
