After NFP on Friday, C-trader live has frozen and after several restarts it stayed that way for more than half an hour. I called my broker and they said it was a program problem, meanwhile MT4 was running fine with the same broker. The gap, slippage you are referring to might be a result of this outage in that time period and not a regular issue under normal conditions. But I agree with your earlier post that they should come back to market with C-trader at a time when it is ready for trading. I might give it one more try but I think I will go back to MT4. I attach the live chartshot of the AUDUSD, 14:30 NFP for me, I am London +1. The next candle you see after the second gap is at 15:09, after the outage I mentioned.

As for Liquid Markets issue. There was a problem on Liquid Markets liquidity provider side, it stopped sending prices to the cTrader Live feed for a while, that's why MT4 and cTrader Demo was working. The broker is aware of this issues.

I was using your Demo account during NFP Friday 5-Jul-13 and was suprised about the ammount of Slippage on AUD/USD - 16 pips!

Was this screenshot made on IC Markets Ctrdaer? We are investigating this issue right now it it looks very strange. You can help us in this investigation by making full chartshot of this chart (using chartshot button on cTrader chart toolbar toolbar).

There was no price gaps or freezes this time, if you tried to trade most probably you would trade successfully this time. It seems that the problem is in live trendbars presentation. If you open fresh application or refresh the chart you will see this picture (plese make original chartshot befor refreshing):

Note that there is originaly collected data in our database, it was not modified/fixed.

Here is raw tick data from this period:

Boolean type parameters are supported now:

        [Parameter("Use Stop Loss", DefaultValue = true)]
        public bool UseStopLoss { get; set; }

The properties are implemented and released in the latest version:

var request = new StopOrderRequest(TradeType.Buy, Volume, TargetPrice)
{
   Label = "6781",
   StopLossPips = 20,
   TakeProfitPips = 10,
};
Trade.Send(request);

Is my suspicion correct that you're not using real exchange rates for backtest, but a fixed value, like the first available value in the backtest?

 

Yes, we use live rate available at the moment you start backtesting. Generally backtesting measures the performance of your strategy itself. If you have two different strategies that have similar performance on EURUSD, conversion to CHF will affect both strategies approximately equally. Note, that broker does not convert funds from you account to the currency you buy or sell, only profit/loss is converted.

It is normal. We use 1-minute bars to generate ticks within a minute, so exact ticks are not the same as you see in real life. If you robots is based on bars/indicators it's ok, but in your case results may be inaccurate. We plan to provide raw tick data for backtesting in nearest future so you will be able to backtest you strategy with the real ticks.

We have checked this issue, it apperas because of default security settings on both Windows Server 2008 and Windows Server 2012. In order to make it possible to install cTrader and cAlgo you need to decrease security level or add our sites to the list of trusted sites like shown on the picture.

Currently cTrader and cAlgo can not work with wine because we use WPF technology that is not supported by wine.

Most probably this issue appeared because it was unable to find or load some external assembly, referenced from a robot. We will add more user-friendly messages in most cases.

The major differences are:

• Robot can trade, indicator can not
• Indicators can be used in cTrader, robots can be run in cAlgo only (we will add an ability to run robots in cTrader in future)
• Robots can reference and use indicators
• Indicator is reinitialized (recreated) every time you change timeframe or refresh a chart. But you can not do this with robot, you must stop it first
• Indicator can not access Account properties (positions, balance, etc) - we will implement this ability in future

Server time method returns UTC time now. Before that it was in your broker's server time zone. The simplest way is to add server time offset to the time you got from Server.Now. For example if my broker's server is located in UTC+3 time-zone I can do following:

	DateTime serverLocalTime = Server.Time.AddHours(3);
	
	startTime = serverLocalTime.Date;
	activeTime = startTime.AddHours(0);
	stopTime = startTime.AddHours(24);

But when you use activateTime and stopTime later you can compare them only with local (adjust) server time.

Another solution is to count activate and stop time in UTC, i.e. I can activate my your robot in 21:00 UTC instead of 00:00 local server time (if my broker's time offset was UTC+3).

We've checkked your bars and can confirm that the reason is the minor difference in prices between live and demo account. To make it similar pleaseensure you do this:

• Open cTrader on PC1
• Login to Live account
• Right click on a chart, press "Refresh" in context menu

• Open cTrader on PC2
• Login to Live account
• Right click on a chart, press "Refresh" in context menu

Prices will be exactly the same after this procedure.
