Yes, it's possible you can backtest a manual strategy on cTrader back tester with a cBot that allows you to execute and manage orders.
Take a look to our Manual strategy tester: https://www.algodeveloper.com/product/manual-strategy-tester/
That's a great piece of software!

I use this code the generate csv files... Then you can dump it to your mysql database! Just scroll the chart back for the time you want the data from, choose the time frame and hit the play button on the bot! It will save it under documents/data/SymbolNameTimeFrame.csv

Hi leoheermoso,
There isn't such a place. Usually known bugs are fixed in the next couple of versions. This is an exception since we are currently refactoring cTrader Automate and we will fix this as soon as we finish.
Best Regards,
Panagiotis
Hello Panagiotis,
Tks for your answer, I am looking forward to this fix!

Is there any place with the know bugs? If now it will be nice to have. I just spent 220 USD in an aws instance at amazon with optimization purposes and looks like the results are entirely wrong. Can you please enumerate know bugs? Tks

Both are backtesting results
These both are optimization results.
I use daily data inside this 1-minute bot, and the parameter attached to daily data is 35 periods and its roughly the period that optimization and backtest begin to behave accordingly, so it makes me think to backtest are not correct pre-allocating the necessary data to correctly load the indicator

Hi cysecsbin.01,
Thanks, we managed to reproduce this. The problem is with the optimization results. The backtesting results are correct. We will fix in in an upcoming update.

Hi, Is this problem solved? I am getting different results between opt and backtests. I think its caused by MarketData.GetSeries that MAYBE is not pre allocating the correct amount of data to initialize the indicators.

Partial close is not supported in backtesting. We plan to support it in the future.
When this is going to happen?

I discovered the problem, i have two rules for order cancelation:
else if (Symbol.Ask > sellprice_) { cancel_orders_by_side(VR_label, TradeType.Sell, VR_label); }
This is for Short pending orders, so whats happens is even with 1.2 ms latency with broker server, broker took 200-300ms to execute request to cancel, this is a infinite time in terms of HFT. So i am pulling pending order out and using market orders instead.
You could include an option to delay execution in backtest like quantconnect have, will make results closer to reality!
ps: Drummond i am using tick data to backtest!
Best Regards

Of course are the same period! othewise this topic makes no sense! What i meant its because January drawdown( that i am still taking) i was able to realize the different results... The backtest was performed 01/11/2017 to 30/11/2017 same period the bot did run non-stop in a ultra low latency vps from forexvps.net.
