Candle sticks with custom data ?

[Edward Arads Wlash]

I was wondering if there is a way to draw candlesticks or bars from custom data like csv file or API feed ?

I know there 2 ways to draw them using histogram like heikenashi candles indicator , or drawing small trend lines with thicker width from open to close price  and trend line with thinner width from high to low  but thats not what I am looking for exactly 

My use case :

I want to draw candlesticks for the stocks that aren't provided by most of the brokers ( and I haven't find any broker who provide those stocks with mt4)

And I want to actually run some analysis using my indicators on those stocks , so I kinda need to manipulate the existing bars/candle sticks to be drawn on custom OHLC data

So is there a way to achieve something like this in mt4 ?  Or am I just pushing it ?

Thank you

On MT4 you can use Offline Charts for displaying OHLC data of other symbols and assets.

On MT5 you can use the Custom Symbols for the equivalent purpose.

Thank you for your response , but can the offline charts be displayed using custom OHLC data from csv or some similar source ?

Did I not just say that the exact purpose of Offline Charts is to display OHLC data from other symbols?

Us the FileOpenHistory() function to produce the Offline Charts. Study the "PeriodConverter.mq4" file for more details and do a search on the site as well. The following thread should also help ...
