Need help with understanding simple EL code

October 23rd, 2015, 07:27 AM

Hello everyone
This is my first post here and I hope this is the correct sub-forum to addess this. I have been studying various EL introductions but I did not get clarity on some statements.
I am trying to understand some EL-Code in order to translate this to my platform. Since I don�t have access to TS to test things out I am reaching out here.
The code is about as follows:

Code

If marketposition >= 0 then begin
	Sell short  (�s1) 1 contract next bar at p1 stop
End

I am reading the above as follows:

if there is no position or current position is long then

enter a short position of one contract as soon as the next bar starts but only if the price is at least as low as p1.

So it will not execute an order in the current bar, right?

Is it also correct that the order remains active until price<=p1? Meaning even if the condition price<=p1 is only met 10 bars later?

Thank you

if there is no position or current position is long then

enter a short position ORDER of one contract as soon as the next bar starts - to sell short if the price of the next bar is at p1 or below. This order will be active for the entire next bar. If it does not fill during the next bar, it will not renew the order for the next bar unless the condition is evaluated as true again.

So, if this is your whole code, if the order is not filled that next bar, at the end of that bar the code will be reevaluated, and since marketposition is still >=0, the order would be resubmitted.

That was really speedy - thank you very much!!

This is exactly the clarity I was looking for. Really appreciate your support!

Also note that the order will be filled at market if price is below p1. You may want to think about this if you are dealing with daily bars. Maybe you need a stop-limit order.

That is a good point, if there is a opening gap. The strategy backtest will show a fill at the open price in this case.

In actual trading, though, the order will be rejected at the broker, since you can't enter sell stop orders that are above the market.
