You can adjust number of CPU cores used for optimization: http://help.spotware.com/calgo/cbots/optimization#resources

That resource slider changes number of threads used for optimization. 100% value means that number of threads will be the same as number of cores.

 

Is cAlgo able to use HyperThreading technology? For example, like in this Intel Core i7-5820K. Or the resource slider just recognize physical cores?

It uses logical cores as well. You can note that resource slider allows you to change resources by fixed step. Number of steps is the number of cores.

can you tell how can i dispose this reader?

Invalid said:

Dispose DataReader when you exit from OnTick. Example:

  using(MySqlDataReader Reader = cmd.ExecuteReader()) 
  {
       // your cool stuff here
  }

Probably database is the bottleneck. You can try the following things:

• Do not establish database connection on every query. Instead of that you can establish database connection in OnStart method and drop it in OnStop method
• Install database on your machine, instead of connecting to remote one
• Try other database engines. There is a chance that this problem is specific for mysql.

RE:

it depends on your brokers, most of them have limit 200 open positions.

I need to be able to have up to 10,000 positions open at all times on large accounts.  Does anyone have any experience with running a large number of open positions on cAlgo or cTrader?

Hi,

I do not know just what to put as many small items instead of one large for long period. always comes out better, and do not need so often to make a decision which way. the same result can be achieved by one position.

Besides insert an image without code is like for me to make any sense.
On the other hand, if you score corresponds to not have to brag about:]

But always backtest everything looks good only in the real world there is no second chance : P (calgo, connection or robot can always suspend at one position always safer)

Bye.

my latest work.

Hello,

You forgot to include your broker's commissions.Keep working.

i am working on equity, any suggestions?

Hi,

You will lose your money without SL! Be careful!

Balance is nice, but you need to concentrate the Equity as well.

If Equity increases together with Balance, well, that's a good strategy.
