iCustom with parameters

[jfitton74]

When using iCustom with parameter array 2147483647 is returned however if I use the method that doesnt take a parameter array I get the correct returned value, it is then using the indicator defaults in the indicator file at this time to simplify testing have been set as 1,3,2.5 ie the same as being passed in through code.

here is the code
string sym = "GBPJPY";
const ChartPeriod timeframe = ChartPeriod.PERIOD_D1;
string ea = "JFTEST";
double[] param = { 1, 3, 2.5 };
const int mode = 0;
const int mode1 = 1;
const int shift = 0;
var result1 = _apiClient.iCustom(sym, (int)timeframe, ea, param, mode1, shift);
var result2 = _apiClient.iCustom(sym, (int)timeframe, ea, mode1, shift);

Am I making a basic mistake or is this a known issue?

I am using v1.43.

There is an error in MQL code of MtApi EA: in parsing arguments of function iCustom.
This error will be fixed with version 1.44

Fixed in PR #297 (MQL5 side) and PR #298 (.NET side):

1. MQL5: iCustom double parameter case had ArrayResize called after the write loop — out-of-bounds write/crash. Moved ArrayResize before the loop.
2. .NET: iCustom int[] overload had "Parameters"/"Params" keys swapped vs what the MQL5 handler expects. Changed to "Params"/"ParamsType" matching the other overloads.

The double[], string[], and bool[] overloads were correct — only int[] and the MQL5 double case were broken.
