Learning EL. Question

May 11th, 2012, 10:10 AM

Hello-

I'm learning EL currently before I get TS. Does anyone know of some java EL compiler that I can use to check the code I write for my examples?

Another question:

I want to go long at the open of tomorrow is the close of today is higher than the open of today and also higher than the high of yesterday but I want to exit the position at the close. Will this work?

Code

if c[0] > h[1]  AND c[0] > o[0]  then begin
Buy Next Bar at open;
sell Next Bar at close;
end;

Thanks

Timot - I do not think there is a standalone compiler to check EL code. I am not sure that it would be very helpful because the compile errors are usually easy to solve but the logic errors can be much more time consuming.

I checked your code and it does not compile because order execution at the close is restricted to "this bar" only. From your code, I assume that you want to use daily bars. Selling on the close of a daily bar will probably work for backtesting. But I do not code this way because I think that it will not work in real time as the market could be closed. I suggest using bars with a smaller time period and specifying a sell time before the market closes.

Thanks Len. So if I understand what you say I better use something like this:

Code

if c[0] > h[1]  AND c[0] > o[0]  then 
Buy Next Bar at open;
If marketposition = 1 then
sell this Bar on close;
end;

Will this close the position on the same bar it was opened?

This is only for daily bar back-testing to start with. I'm to much of an amateur to go real-time intraday any time soon.

Timot - Very nice. Just remove the end because there is no begin. See chart below.

Personally, I avoid the use of marketposition because I have had real-time problems (I don't know why). But if I recall, it works fine in backtesting.

Code

Buy Next Bar at open;

should be written as

Code

Buy ("B1") Next Bar at market;

you cannot sell Next Bar at close

because in real time, you could not know that specific tick is the close until the close has happened.

ie. the best you can do is the sell at the tick AFTER the close, and that would be the open of the following bar.

@Bimi - This is just weird.

Both of your comments are incorrect and you should consider deleting them. The chart that I posted demonstrates that Timot's code does what he wants to do with backtesting.

Hi @Timot,

MultiCharts also uses Easy Language (it is named Power Language but it is basically the same).

You can download and use MultiCharts free version to test whatever EL code you wish.

In his defense it is sort of correct.
It all depends on how the op wants to trade?
Trying to get the very last tick price of the day would be near to impossible but if you are looking to see if your in the ball park with your system, then the market on close is close enough .
Who knows, maybe the user will sit at his pc and hit the close trade button with seconds to go before the close of the day.
