Hello everyone,

I'm working on a strategy that basically has some levels and I need to know where the price is in relations to those levels.

For example I have 5 levels and I want to know when the price is between 1 and 2, 2 and 3, etc...

the snapcode of the interested part is:

 

Code

// at the beginning [IntrabarOrderGeneration = true] .......some inputs... variable: intrabarpersist burntIndex(0), ..... ..... here all level prices are defined ( example level_1 = 2780, level_2 = 2740, level_3 = 2700, level_4 = 2670,level_%= 2640 ) ..... if price < level_1 and price >= level_2 then begin burntIndex = 1; end; if price < level_2 and price >= level_3 then begin burntIndex = 2; end; if price < level_3 and price >= level_4 then begin burntIndex = 3; end; if price < level_4 and price >= level_5 then begin burntIndex = 4; end; if price < level_5 and price >= level_6 then begin burntIndex = 5; end;

With this code I was hoping to get the position of the price between levels by changing the burntIndex variable and UPDATING it in realtime...

But using a lot of prints to debug I discoved that it performs the operation succesfully ONLY at the start of the session (probably just the first time that the code is executed)... I tried to print the burntIndex value at several different hours of the day but it REMAIN THE SAME for ALL THE DAY... it just reset at the morning....

The code above should be executed on EVERY tick (IOG is true) so I think I'm really missing something stupid here but I can't come up to a solution.

btw: there are no ONCE piece in front of this code.

Any ideas on WHY it doesn't update the burntIndex during the day when the price is moving?

Any suggestions are appreciated,

Thanks and Best Regards

Dvdkite,

without the full code or at least code that can be used to reproduce the behavior I am afraid it's hard to tell.
Check your level values and the value for price using print statements for a few bars to see if they actually hold the values that you think they do.

Hello ABCTG,

the piece of code with the 5 "if" is in the main part of the strategy and it is supposed to work indipendently to the other part of the code. I'll try to add the other parts without all details..

 

Code

[IntrabarOrderGeneration = true] inputs: debugMode(true), Price( Close ), StopLoss( 30 ), ProfitTarget( 15 ), // and some more inputs.... variables: intrabarpersist burntIndex(0) //..... //..... here all level prices are defined ( example level_1 = 2780; level_2 = 2740; level_3 = 2700; level_4 = 2670; level_5= 2640; //..... if price < level_1 and price >= level_2 then begin burntIndex = 1; end; if price < level_2 and price >= level_3 then begin burntIndex = 2; end; if price < level_3 and price >= level_4 then begin burntIndex = 3; end; if price < level_4 and price >= level_5 then begin burntIndex = 4; end; if price < level_5 and price >= level_6 then begin burntIndex = 5; end; // then if I try to print the burntIndex at different time of the day if time = 815 then if debugMode then print(" burntIndex at 8:15 = ", NumToStr(burntIndex,2)); if time = 1200 then if debugMode then print(" burntIndex at 12:00 = ", NumToStr(burntIndex,2)); if time = 1600 then if debugMode then print(" burntIndex at 16:00 = ", NumToStr(burntIndex,2)); if time = 1900 then if debugMode then print(" burntIndex at 19:00 = ", NumToStr(burntIndex,2)); // it ALWAYS GIVE ME THE SAME VALUE FOR ALL THE DAY!!!!

I cannot find other relevant part of code because the other part are UNRELATED with those prints.
I need the burntIndex to perform diffentent kind of actions on the actual level...
But as I said it just print the burntIndex related to the price value at the opening of the sesssion..

Any idea??

Thanks

Dvdkite,

I would check if the conditions are actually triggered and when by adding print statements within each begin... end block.

 

Code

if price < level_1 and price >= level_2 then begin burntIndex = 1; end; if price < level_2 and price >= level_3 then begin burntIndex = 2; end; if price < level_3 and price >= level_4 then begin burntIndex = 3; end; if price < level_4 and price >= level_5 then begin burntIndex = 4; end; if price < level_5 and price >= level_6 then begin burntIndex = 5; end;

You might want to add the print before you set the value for burntIndex as this would allow you to check for
if burntIndex <> 1 then Print... for the first check and so on for the other checks with adjusting the number of course. This should tell you when and which level triggers and not clutter the output too much.
Based on that you can investigate things further.

Did you check your level values and the value for price using print statements for a few bars to see if they actually hold the values that you think they do? What was the result?

UPDATE:

Hello again, I made one thing to solve the problem... I've removed all the code BEFORE those code above and surprisingly the burntIndex was working!!! So I checked the section where I set up the level values depending on the date... at the end I came up to the solution that was so so easy...

I had to put INTRABARPERSIST even in front of every level variables... that solved the problem!!

I didn't think it was necessary to declare also the level variables as intrabarpersist because they are values that are updated just once at the starting of the session... Now I know!

Thanks for the tips

Best Regards,

David

David,

you are welcome and I am glad to hear that you figured it out.

Variables don't necessarily have to be intrabarpersist in an intrabar order generation strategy. However if you update them during the bar and want them to keep the value they have to be declared as intrabarpersist. Otherwise they will revert back to the previous value at the end of the code cycle.
That's why I suggested checking if the level variables actually hold the value that you think they do.
