Low number of bars in offline charts (M2 timeframe)

 

Hello, everyone! 

Sorry for such a beginner/newbie question, but I'have been struggling against this problem. I'm using a renko chart generator and I need to attach it in a M1 chart and then open a M2(offline) chart. The problem is: 

I don't know why, but recently the number of bars available is very low, like, something between 50~200. I use an indicator that I use at least 1000 bars for some kind of analysis. 

Does anyone here know how do I increase the number of bars in the offline chart? This is a bug?


Thanks and I hope you all have a nice day!
