Well, I have to say this: After working for 2 days only, cTrader platform crashed and was shut down automatically while running on the above mentioned Google Computing Engine Cloud.

Things do not look as reliable as they are advertised, obviously.  I don't know whose fault it is (Google or cTrader), but how can I now be sure that my cBots will be running non-stop for months as my strategy requires?  The setup has not lasted even for a couple of days... Be aware...

You can choose there Windows Server (2008 or 2012) and lots of other operating systems.

By the way, Amazon provides a similar service, and their free test period is 12 months (!).

Google Computing Cloud is great! The latency to Pepperstone is actually 4 ms :) I've got 2 processors (2 x 2.5 GHz) and 8 Gb memory.

This is what I found: Google gives 60 (!!!) days free test period, you can get a computing cloud and run a quite powerful computer for backtesting and optimization using Remote Desktop Connection. I do it now. Even after the free test period, the charges are quite low and flexible. By the way, latency to Pepperstone is 6 ms :)

I have a question about Max Equity Drawdown (%) vs. Fair Stop Out in cTrader (which is 50% for my account).

Do I understand it correctly that if Trade Statistics after backtesting a cBot show that Max Equity Drawndown is 55%, it means that if I were running this cBot in live account, I would be stopped out?

Thanks!

Dear Trader,

If you don’t want your cBot to open a position in a certain interval you could write an if-statement to prevent it from happening.

The following code snippet illustrates an example where the if statement checks if the minute of the hour is the 11th. if the condition is true then it prints "hello" in the log.

if (Time.Minute == 11)
{
    Print("Hello");
}

Additionally, we would like to inform you that we do not provide coding assistance services. We more than glad to assist you with specific questions about cAlgo.API. You also can contact one of our Partners or post a job in Development Jobs section for further coding assistance.

Thank you

Dear Trader,

We are not sure we understand what do you mean. Could you please explain us in more detail what you are trying to do?

Well, I analyzed the backtesting results and the "entry by hours" show me that the trades opened during certain hours generate losses, not gains. So, I want to add a code that will prevent a cBot from making any entries during these hours. Can you please help me with the code? Or give me a link where it is already explained. Thank you.

The code executes only within a specific time interval of the day. The input parameters for the start and stop time are in hours. For instance, if the Start Hour is 10 and the Stop Hour is 12, the robot will only execute when the server time is between 10am and 12am.

Hello!
How can I explain to a cBot that during optimization or backtesting it should refer not to the current server time hours, but to the server time which the historical tick data from the server are dated with?

The slider is certainly to the max.

I found a way out: I run several instances of backtesting or optimazation at once, 2-3 processes are able to use 100% processing power. 1 process is not enough.

I also experience frequent disconnects, even during backtesting or optimization. After logging out, closing the application and starting it again, it works again, for a while....

Why simply not use Wise Memory Optimizer (it's freeware) by Wise Cleaner? It's sitting in the tray and can be set up to clean up the memory periodically.

CPU is the primary player in backtesting.

Then why cAlgo now does not utilize 100% processing power now?

I have Intel i3 4130 @ 3.40 GHz and 4 GB of memory (Windows 7 Ultimate, 64 bits).

But when backtesting is running, the workload upon the processor is only 40-50% and memory is only 45-50% full.
