Preload bars error messageView all attachments
08/16/2019 at 2:25 PM #104865
Even after i increase the defparam preloadbars = 5000 i still get the error message and my automatic code is rejected. I have tried setting to 0 and also removed it totally and my code still stops. The error message is the basic …please increase the number off preloaded bars with instruction DEFPARAM etc etc
Code works fine on back test – has also previously worked as automatic code before i have increase some filters in the code which is now causing the problem.08/16/2019 at 2:37 PM #104866
Try to increase to 10,000 (max. allowed).
In case you use very high period numbers for indicators, try decreasing them.
As a final resort you should post your full code to be able to replicate those messages.08/16/2019 at 3:25 PM #104871code with

Restarted everything and reloaded and error happens again .
I can back test no problem with the code without errors its when i then put it live – it loads it then rejects it after a few minutes.
im running it on the DOW on 1 and 3 minute time frames.08/16/2019 at 5:34 PM #10488108/16/2019 at 6:13 PM #104886
Backtest is very slow, instead!
I agree … maybe the OP just chose the wrong Username! 🙂 🙂
I will try it on Demo Forward test and Report back!
EDIT / PS
Yep rejected 3 times with and without the PreLoad bars I get same error message … Increase PreLoad bars etc etc.08/16/2019 at 6:55 PM #104890
I reckon it’s timing out on Forward Test (code taking too long etc) and the error message is meaningless?
On Backtest there is probably a longer time out period and that is why the code eventually gets there in Backtest??
Basis for an easy worded Tech Report? I suggest …

- System won’t run on Forward Test … please can you tell me why?
So u suggest I ask tech support with that so I therefore will with yr suggested comments . back testing is very slow due to all the requirements it has to test … let’s see if they have a solution .. ? Seems strange to me08/16/2019 at 8:02 PM #104892
Yeah we all learn more when we make mistakes, we need to know what the limits are on time for code to run and PRT may learn something also during the investigation ?
It may be something simple anyway that is making it real slow?
Results (attached) look promising on DJI 1M, spread = 4 attached so it is worth keeping the code as is if it will run okay?
Press Ctrl + M when you are seeing a Chart on the screen and follow the bottom option … Tech Report.

There is something odd about that code even outside of PRT … as soon as have it up on my screen in this Forum and I am scrolling over the code … my scroll button works real slow like when I am running out of RAM.
I reckon it’s that Username the OP has … he’s jinxed himself!!! (joke! 🙂 )
But not joking about the slow mouse scroll.08/19/2019 at 1:38 PM #10507008/27/2019 at 10:11 AM #105637
Just spent the last hour or so removing various snippets / conditions / variables etc in an effort to stop this System being rejected and showing an error message that has nothing to do with the rejection!
Below is the fix. Seems it maybe was timeout error as I had suggested above?
Code was using ADXPeriod and ADXp for the same value, but ADXp was not defined anywhere in the code.12Line 36adxp=adxperiod (not adxp=adxp)
