RE:

I just tried your suggestion, logged out and then back in, ran backtest, same results... no data forward past 7/16/15

Dear Trader,

Could you please remove your backtesting cache which is located in the following path:

C:\Users\%UserName%\AppData\Roaming\%Broker Name% cAlgo\BacktestingCache

Can you give the same type example of reading from a file back into cAlgo?

If I use tick data, the closest day I can run a backtest to end is two days ago... why?

Why can't I backtest tick data running all the way up to present day?

admin?

I'm using exact code & parameters & timeframe... work on live account but only sometimes on demo.... help support?

Not sure why but the same code executes backtest trades in Live account, but executes NO backtest trades in Demo account... using same code and same settings

Looks good Balena, but can you run it for longer duration ( 2-3 years ) and let us aware of commission and spread assumptions.

this is using tick data... commissions could be 10-65/million... all work

other years are also profitable...

you can use/modify these...

          //if (Server.Time.DayOfWeek == DayOfWeek.Sunday && Server.Time > stopTime)
            //return;

            //if (Server.Time.DayOfWeek == DayOfWeek.Monday && Server.Time > stopTime)
            //return;

            //if (Server.Time.DayOfWeek == DayOfWeek.Tuesday && Server.Time > stopTime)
            //return;
            
            //if (Server.Time.DayOfWeek == DayOfWeek.Wednesday && Server.Time > stopTime)
            //return;

            //if (Server.Time.DayOfWeek == DayOfWeek.Thursday && Server.Time > stopTime)
            //return;        

            if (Server.Time.DayOfWeek == DayOfWeek.Friday && Server.Time > resetTime.AddSeconds(ySeconds))
                return;

            if (Server.Time.DayOfWeek == DayOfWeek.Saturday)
                return;

tSpotware said:

Our tests show that there is no any significant difference between CPU consumption in cAlgo 1.23 and latest cAlgo 1.24. Probably performance issues that you observe do not relate to the latest update.

We deployed latest version to all our brokers. Different CPU consumption for different brokers could be caused because of different price feeds. For example, if broker provides ticks more frequently your indicators and cBots will require more CPU resources to handle all incoming ticks.

there is a problem for sure... it's not the bots... i see same cpu issue running 1hr as I do running 1 tick

If you refer to the quality of generated ticks we have great news for you. We are preparing tick data backtesting to be released. By using tick data backtesting you will be able to test your cBots with historical spreads. Furthermore, in tick data backtesting Bid and Ask prices come asynchronously with millisecond precision.

 

 

awesome news...

RE: RE: RE:

One quick question... I have both a demo instance and a Live instance up on same cpu 

when I make changes to one (add a robot, delete a robot, add code, rename, etc) the changes are seen in both instances

so how can I have different robots for each instance?

could you give more details on how you run a parallel system, no logic of course, just can't figure out how to have different robots for each instance

thanks

Cerunnos said:

You only need two different cAlgo instances on an operating system because the API does not allow for switching between accounts. That with the CPU should not matter, but you better inform at Scyware (support@scyware.com )...

Hi. I'm using a parallel system consisting of a demo and live account. If the demo robot (seperate cAlgo instance) is successfull, a boolean variable will be set to true and the live robot will be unlocked. The communication between the robots is done over robolink (very simple - just a few lines of code are necessary), but you can also write a value into text file with StreamWriter and read it from the other robot with StreamReader. Hope that helps.

I currently tab between demo and live on the same cpu...

So if you don't mind sharing...

1. if I use the RobotLink will it work if I currently tab between demo and live on the same cpu; ie "cpu 1"?

2. do I have to run demo on "cpu 1", and live on "cpu 2"?

Thanks Again!
