MT4 Timeframes

[Jefferson Judge Metha]

In mt5 we have additional timeframes like M2 H2 etc. 

Is there a way on a life chart to get these bars in Mt4. 

[Will post my code currently on mobile phone]

I tried to create arrays for OHLC and then to calculate bars for e.g M2 and the populate the arrays. 

But I have a feeling I am doing unnecessary work

Find a offline chart generator (for Build 600+)

Aside from Offline,Renko and some other custom TFs builders - the only one and first coder i saw in the wide wide net (coding world) "Mladen Rakic" who invented the custom TFs code for MT4 - unfortunately rare peoples know of this creation,as example "ex4" file format can be posted for to test/check/exercise by users but i doubts will be removed/deleted by mods as they only allow mq4 - :)
