Hello everybody
In a system tester, I want the exit to be X days after the long or short position
For example,
Buy Order : c > ref(c,-1)
Sell Order : exit the “Buy Order” after 3 bars
Can anyone help ?
Thanks
Vasilis

Hi Vasilis,
One way of doing that is to use the ValueWhen function. Following up on your example:
Buy order: c>ref(c,-1)
Sell order: BarsSince(ValueWhen(1,c>ref(c,-1),C))>3;
However, there is a very big deficiency with the ValueWhen function that I know of and that is if the condition(c>ref(c,-1)) is repeated after you buy then the BarsSince function will count from the most recent occurrence of the expression c>ref(c,-1). This is the meaning of 1 in the Valuewhen syntax. If you put 2 for example, it will look not from the most recent occurence but from the one before that.
That being said, if the condition of the buy order occurs rarely you can be quite comfortable with this sell expression.
Maybe some of the more MetaStock - savvy guys on the forum can help you out further with more complex techniques.
Cheers,
VT
