Hi! Could you send me the instructions on how this EA works, how to configure and optimize? I have the free version and I'm interested in the paid one. Thanks 

I have been using the free version of grid harvester EA for about a month now. I am VERY happy with it so have begun using it for the core of my trading.

Now considering purchasing the full version though I have run into a problem in that last week. The EA is stopping at error:

"Array out of range in 'mt4_grid_345_free.mq4' (1368,26)"

I have tried reloading many times and altering the settings but I can't work out what is causing this error, it is stopping my trading functioning. And I don't have access to the source code to check what that line is for.
I would greatly appreciate any help, thanks.

I have been using the free version of grid harvester EA for about a month now. I am VERY happy with it so have begun using it for the core of my trading. 
BUT recently the EA keeps stopping at error:
"Array out of range in 'mt4_grid_345_free.mq4' (1368,26)"
I have tried reloading many times and altering the settings but I cannot work out is causing this error.

So I purchased the full version (have been considering this), but got a similar error:

Array out of range in 'mt4_grid_harvester_v436.mq4' (3663,26) 

This has stopped my trading functioning, very frustrating. And I don't have access to the source code to check what that line is for. I am using mt4 (v4.00, build 840).

PLEASE HELP!

please send me a SET file, we will investigate this. over 50 copies of Grid Harvester has been sold and noone reported this error since now, but maybe there is something is the set file, that causes it. 
If we find it I will try to make impossible for this error to occur again, (limiting the variable range) but i need this SET file.

Good day.
I would like some information, how to configure to block the auto lot.
I need fixed lots.
Kind Regards.

youu need to DISABLE (set to FALSE) money management option.

Then all lots will be set manually in option LOT SIZE.

 2015.10.28 23:07:00.984 TestGenerator: unmatched data error (low value 1.54826 at 2015.10.15 13:00 is not reached from the least timeframe, low price 1.54833 mismatches)

this seems like back-tester error. Please attach more details about your test (send me set file and screenshots on private message)

Is ther any option here for short term ? some times longterm is scary because of unpredictable market..

( Im buying it soon, but not now. ), Doing some testing..

depends on the period of time you choose. Here are example videos on how to create pre-sets for oscillation and trends:

Good evening

 It's me again...

Could you send me the instructions on how this EA works, how to configure and optimize? I have the free version and I'm interested in the paid one, but I'd like to understand better how it works. Thanks again!

please contact me in a private message. I am almost ready with the new version - 5.11. Here are some shots:

An update will be ready within a week and I also plan the new PDF instruction to be done by then. 
Grid harvester will have basic yourAI module - the module that lets you simply program your own open/close logic with use of almost any indocator.
For more advanced ai - combinations of indicators, filters new version of Grid Harvester PRO with full YourAI module will be added.

If you want them faster contact me in a private message. 

I sent you links to tutorial videos in the private message.
Here is instruction to 3.x version:
