I had no errors since start. It seems, bug is fixed.

Thank you.

Are you going to add backtesting on Renko-charts?

Hi Andrii,

At the moment only Spotware cTrader Beta contains the fix. Your cTrader should be automatically updated.

I've started my Bot. Will let you know how it goes soon.

Regarding the RSI indicator, the two cTrader instances do not necessarily have the same price history.

You're right, charts are different.

How to connect both terminals to one liquidity provider to have the same quotes?

It's renko!

I checked bars extremums, they are the same:

Both RSIs based on Close prices and have period of 14

The same bug in the latest beta — renko cahrt doesn't update after start: https://youtu.be/jxgssXaX1ew

I've modified bot to use 1st and 2nd bars because new renko chart draws zero bar while it formes, but first problem is frozen chart.

Code for newest cTrader:

        public double StopLoss { get; set; }

        [Parameter("TP (in renko)", DefaultValue = 4, MinValue = 1, Step = 0.1)]
        public double TakeProfit { get; set; }

Please download it and check if the behavior you reported is still reproduced or has been fixed. This version will be pushed to brokers soon. If the problem is fixed there, there is no reason to investigate further.

Ok, I'll try.

But this bug is floating, so I need time to catch it.

Bot worked without pauses ever since I wrote the post.

It printed old values of indy till 07/03 20:17 and then started to print correct values (and trade, of course):

First time it printed invalid value of RSI[0], but then started to work correctly.

Any ideas how to fix it?
