There are no guaranties of internal cAlgo/cTrader code to be reentrant. With the approach of the timer, I would have moved all of the custom code into a separate method. That method should be called from OnTimedEvent(), OnTick() and OnBar(). That method should include some sort of synchronization primitive to guard against simultaneous invocation from OnTick()/OnBar() and from OnTimedEvent().

But even that does not guarantee that you do not go through some non-reentrant internal code paths when executing that method from OnTimedEvent().

AlexanderRC is right. Please avoid of using Timer classes.

In future we will introduce cAlgo.API.Timer which will guarantee that only one thread is working with API objects.

Hello, 

We will consider your comment about the location of percentages in the fibonacci tool. You can save a default colour for the fibonacci tool by Right Clicking on it's settings and selecting "Apply as default settings"

We have checked everything one more time. History is supported in backtesting.

So if using a timer isn't safe, data isn't updated inside a loop and there is no event triggered for pending orders, how do you suggest that one writes code to be instantly notified of changes to pending orders?

You can not implement it in current version of API

Hello Admin

today while opening cTrader I was asked to download updates of 12.5 mb...usually, after installign updates it shows what's new....but this it didnt. What novelties are installed lately?

note: I had installed February updates prior to this one.

cTrader had to to be updated, because we extended cAlgo.API. History collection was added.
cTrader was optimized and several minor issues were fixed in last release.

At the moment you can use only Positions.Opened and Positions.Closed events. You can post your idea to vote.spotware.com.

System.Timers.Timer uses ThreadPool threads. Please avoid using System.Timers.Timer because while you are accessing cAlgo.API objects from timer's thread, cAlgo could decide to update such objects from another thread. In such case there is a possibility that data will be corrupted and entire application could fail.

We are going to implement cAlgo.API.Timer which will guarantee that only one thread works with API objects per time.

We use "Bytes Received" and "Bytes Sent" performance counters. By some reason they are missing on your machine.

I would like to make the move from MT4 to cTrader/cAlgo but tick-testing is a must-have. It's a deal-breaker for me as long as it's not available -- is there any estimate regarding when tick-testing would be implemented in cAlgo?

This feature is in our short term roadmap. We are going to release it in couple of months.

There is no such functionality at the moment. We have plans to support enum parameters in the future.

cTrader Web doesn't support custom indicators. You can use custom indicators only in desktop version of cTrader and cAlgo.

No, it wasn't. Currently we are not going to remove such limitation.

If you want to reuse some code it is recommended to extract such code to class library and reference it from other cBots.

OnTick method is invoked when platform receives new quotes for the corresponding symbol.

Using of System.Threading.Timer class is not recommended, because its callback is invoked in different thread, while cAlgo.API is not thread safe. It could cause crash of application.

If you want to invoke OnTick handler more frequently than ticks come, you can subscribe OnTick handler to MarketDepth.Updated event.

For example:

protected override void OnStart()
{
  MarketData.GetMarketDepth(Symbol).Updated += OnTick;
}

In this case OnTick handler will be invoked on any update of DOM.

You can use the following code snippet:

var buyCount = Positions.Where(p => p.TradeType == TradeType.Buy).Count();
var sellCount = Positions.Where(p => p.TradeType == TradeType.Sell).Count();
