Big problem i'm having with MT4 Renko charts

Please see the Pic below. Sorry I just quickly made this as I am not able to get on MT4 atm.

I have nearly completed my own system and just need to tweak it but I am having major problems with the Renko block as this keep happening. Once 1 block is out of sync the next block normally re syncs… But Yesterday I noticed a block went passed its 25 pip limit and kept going… and when I get disconnected, a new block may or maynot form. I canno have this as I need a reliable system.

I no many people use Renko charts in MT4 so please, how do you keep it working without deleting the History and setting it up every single time…

thank you

Anyone :frowning: I don’t know where else to inquire and I really dont want to stop using Renko because of this problem.
