Debugging a MT4 MTF ichimoku converted to MT5

Icham Aidibe 2014.01.23 05:56

Hello there,

As I am a newbie in mql coding ... is there anyone to help debugging this code from 31 errors ?

It's a public & free indicator & have to stay free for MT5 so ... just avoid the "post in the jobs" ;)

You haven't converted anything, you have just bolted some rubbish on to the end . . . where is your "emulation" of iBarShift() ? where is your "emulation" of IndicatorCounted() ?

Use the Jobs section and specify that the source code must be provided and that it will be open source . . .

See this article Migrating from mql4 to mql5 and...

Transferring Indicators from MQL4 to MQL5

2010.07.28

www.mql5.com

This article is dedicated to peculiarities of transferring price constructions written in MQL4 to MQL5. To make the process of transferring indicator calculations from MQL4 to MQL5 easier, the mql4_2_mql5.mqh library of functions is suggested. Its usage is described on the basis of transferring of the MACD, Stochastic and RSI indicators.

@RaptorUK : May you ? (no open source in the jobs section)

May I what ? write your code for you ? nope, sorry, I don't have time and my mql5 is rusty to say the least . . . as I said use the Jobs section and make it a condition that the code will be open source . . . is it just that you don't want to pay ?

It's not. Open source is open source. I was mostly wondering if I had to ask author permissions before using his codes.

Open source doesn't mean free.

The code you posted is copyrighted, it's not really the same as open source.
