Exit after n bars

[asi001]

Hi
I want to exit trades which have been open for >9 bars.
(Therefore, no trade will be longer than 10 bars)
E.g. If trade has been open >9 bars since signal, exit position.

What code do I use to get the result?
Where do I put the code? Under Initialize() or OnBarUpdate() ?

Would also be grateful if you showed how I enter a trade if 3 bars have elapsed after a signal has been made.
E.g. If it has been 5 bars since Close > SMA, enter Long.
And If it has been 5 bars since Close < SMA, enter Short.

Hi Jessica,
I am not a programmer but I feel this is an easy one so a programmer wouldn't mind doing it for me.

Hello asi001,

Thank you for your note.

To exit your position after a specified number of bars, I suggest using the BarsSinceEntry() method which allows you to return the number of bars that have elapsed since the last specified entry. You will want to utilize BarsSinceEntry() from within the OnBarUpdate() method which is called whenever a bar is updated. In contrast, the Initialize() method is called only once when starting a strategy.

I've provided a link to the BarsSinceEntry() page on our Help Guide for additional information on how to work with this method in your programming logic:

Please let us know if we may provide further assistance.

Thank you Chris,

how about how I enter a trade if 5 bars have elapsed after a signal has been made.
E.g. If it has been 5 bars since Close > SMA, enter Long.
And If it has been 5 bars since Close < SMA, enter Short.

Hello asi001,

Thank you for the reply.

For your example of entering a position after 5 bars have elapsed since entry, you would want to utilize the following code within the OnBarUpdate() method:

if (BarsSinceEntry() > 5 && Close[0] > SMA(14, 3)[0])
EnterLong();


if (BarsSinceEntry() > 5 && Close[0] < SMA(14, 3)[0])
EnterShort();

This is just a code sample, however, and is intended for educational purposes. You would still need additional custom programming to be written into OnBarUpdate() for placing your entry orders for example.

Please let me know if you have any additional questions.
