Metatrader 4 market expert advisor valuation error
Hey, I have been developing an EA for a while now and wanted to publish it on the Metatrader 4 market.
The EA works %100 on live, demo and back testing. But when I Send the EA in for product valuation I get a report stating "ordersend error 131"
I have been through the coding and read up about error 131 and I can't find any problem.
All my lots and lot sizes have a values that are reasonable and nothing odd.
If anyone has a solution or has experienced the same and figured out how to fix this small issue, Please inform me.
Here is what I get

as the ea is working on live, brackets are set correctly (cross-check / count number of brackets open/closed)?
Did you check the lot sizes (especially the micro-lots?) - is the lot size normalized? Any problem with lot sizes (different brokers, account (cent), currencies might cause issues) will cause such an error.

thnx for the reply.
Will have a look at it. It might be because I have only been using micro-lots with two brokers. thnx for the input.
This will help me greatly

Your code should always check the broker's conditions for allowable volume/lots. Use the "SymbolInfoDouble()" function to obtain the correct details for:
SYMBOL_VOLUME_MIN
Minimal volume for a deal
double
SYMBOL_VOLUME_MAX
Maximal volume for a deal
double
SYMBOL_VOLUME_STEP
Minimal volume change step for deal execution
double
SYMBOL_VOLUME_LIMIT
Maximum allowed aggregate volume of an open position and pending orders in one direction (buy or sell) for the symbol. For example, with the limitation of 5 lots, you can have an open buy position with the volume of 5 lots and place a pending order Sell Limit with the volume of 5 lots. But in this case you cannot place a Buy Limit pending order (since the total volume in one direction will exceed the limitation) or place Sell Limit with the volume more than 5 lots.

How to calculate lots using multiplier according to number of opened orders?
Fernando Carreiro, 2017.09.01 21:57
Don't use NormalizeDouble(). Here is some guidance (code is untested, just serves as example):
// Variables for Symbol Volume Conditions double dblLotsMinimum = SymbolInfoDouble( _Symbol, SYMBOL_VOLUME_MIN ), dblLotsMaximum = SymbolInfoDouble( _Symbol, SYMBOL_VOLUME_MAX ), dblLotsStep = SymbolInfoDouble( _Symbol, SYMBOL_VOLUME_STEP ); // Variables for Geometric Progression double dblGeoRatio = 2.8, dblGeoInit = dblLotsMinimum; // Calculate Next Geometric Element double dblGeoNext = dblGeoInit * pow( dblGeoRatio, intOrderCount + 1 ); // Adjust Volume for allowable conditions double dblLotsNext = fmin( dblLotsMaximum, // Prevent too greater volume fmax( dblLotsMinimum, // Prevent too smaller volume round( dblGeoNext / dblLotsStep ) * dblLotsStep ) ); // Align to Step value
Please read the documentation on:
131
ERR_INVALID_TRADE_VOLUME
Invalid trade volume
Tnx for the reply.
What I can make out is that "NormalizeDouble" is a big issue?
And looking at this part of the coding it is causing the issue?

I have already stated NOT to use NormalizeDouble() and even provided code showing you the correct way to do it.
Please see my previous post and please always use the SRC button to add code as I have done now for your quote.
PS! The example code I provided works for both MQL4 and MQL5!

This is the original coding. I am just pointing that I now found the problem.
