Help! Strategy cuasing looping effect in live sim

[markp77]

Hi.

I have written a strategy which utilizes the Darvis Box Theory. In backtest it looks fine, but in live simulation it often enters into a looping buy/sell pattern which completely decimates profit in a matter of seconds. I was wondering if someone could help me fix this.

markp77,

Try running it with CalculateOnBarClose = true. Otherwise you will want to reprogram your strategy to prevent reentries constantly. You can use something like this:

if (BarsSinceEntry() > 1)
     // Then allow for entries/exits;

I've tried with calculate on close to no avail. I have now added the BarsSinceEntry greater than one to my exit signals and will try that. I'll get back to you once I've determined whether it will work or not. Thanks for the help

If you have multiple entries and exits it may be advisable to use unique signal names for your entries so you can tie the conditions together with the BarsSinceEntry().

Say your signal name was Long1.

if (BarsSinceEntry("Long1") > 1)
     ExitLong("Exit-Long1", "Long1");

Something like that.

I've encountered a problem with using the bars since entry/exit method.

Say I have a script in which I dont want to enter into another trade until 5 bars have passed since the exit. However, when I start this script, it never enter into a trade to start with because it cannot fulfill the requirement of exiting a trade. How can I get around this?

When you have never entered a trade before BarsSinceExit() will return a -1. What you can try is using an || for "or" to combo your conditions like this:

if (BarsSinceExit() == -1 || BarsSinceExit() >=  5)
     EnterLong();
