LastValue also works

I now sync the different timeframes and symbols using  the function Spotware provided as a workaround:

 private int GetIndexByDate(MarketSeries series, DateTime time)
        {
            for (int i = series.Close.Count - 1; i >= 0; i--)
            {
                if (time == series.OpenTime[i])
                    return i;
            }
            return -1;
        }

And to sync the different timeframes and symbols i start the method Calculate with:

int XXXZZZindex = GetIndexByDate(_XXXZZZ, MarketSeries.OpenTime[index]);

Within the indicator you always calculate on [index].

double t = _XXXZZZ.Close[XXXZZZindex];

Within the robot you can use .LastValue and above method works fine.

Double.IsNaN

With double.IsNaN( double ) you can test on NaN as a value.

With double d = double.NaN; you can set an indicator to NaN if it has no value.

double d = double.NaN;

if( double.IsNaN( d ) )
{
      // Nul value
}

That works

The test with GetIndexByExactTime gave no result. The workaround works fine. Thanks. That saves me a trip down memory lane, into the dark ages of MT4.

Work around

Is there really no other work-around that fixes this, cause now i gotta switch to MT4 to get the robot running and we wouldn't want that. ;-)

patience

In the tests i just ran, results were positive. But that might be a coincedent.

So just sit back and wait for the update that contains GetIndexByExactTime.

RE: Time Shift Bug

unjeffer said:

I tried to check if the values were NaN but they are actually just wrong. I think they are just older than how they should be, probably the indicator is not updated on every candle so the value of the bands at the last index turns to be an older value.

Each symbol and marketseries needs its own index. See the solution of my problem here. Maybe this works for your algo as well.

RE:

Spotware said:

You can try this on Spotware cAlgo. The method will be available in the next release.

Fixed it by calculating the index-difference:

_XYZindexShift = MarketSeries.Close.Count - _xyz.Close.Count;

And later on use the same indexShift to get the right index.

Thanks for the tip.

RE: No such method

Spotware said:

You need to translate the index from one series, the one of the chart, to the another. There is a method GetIndexByExactTime

            var indexXyz = xyz.OpenTime.GetIndexByExactTime(MarketSeries.OpenTime.LastValue);
            Result[index] = xyz.Close[indexXyz];

 

It sais there is no method by the name of GetIndexByExactTime...

Same BUG?

Look at /forum/calgo-support/2069?page=1#2

Looks like the same bug. For the smallest timeframes 1m to 3m things are OK, for week and month also.

Test the return values of your indicators in the robot. They probably are NaN. As BB calculates averages, the values of BB are wrong as they are partially based on NaN-values.

Multi Symbol

i forgot to mention: it is an indicator based on more than one symbol.

[Output("Main")]
public IndicatorDataSeries Result { get; set; }

MarketSeries xyz;

protected override void Initialize()
{
        xyz = MarketData.GetSeries("USDJPY", MarketSeries.TimeFrame);
}

public override void Calculate(int index)
{
        Result[index] = xyz.Close[index];
}

RE: Templates and trendlines

Ztop said:

Just so you know. Having something like that cuts my work  time down dramatically.  It reduces my work time by 2/3rds. When you plot a ton of charts that saves a significant amount of time.

Other than that I love your platform. Especially the web platform.

I can watch a ton of charts on chrome by using revolver add on. It rotates through each open chart with a 5 to 15 second intervals. 

So you can use two monitors to do what others use a ton of monitors for.

Now that is a useful tip.

Would you happen to know such an add on o=for Firefox as well?

But I'm the opinion that position.Netprofit includes already commissions...

 

Thanks :-)

Yes, you must double the commission to calculate total costs of the trade.

cTrader stuck

Last friday my cTrader as well as cAlgo refused to close trades. No errors, just no actions. Had to open the webtrader to close the trades. Less profit alas.

Excel export on runtime

It's quite easy to mine data and export them to a CSV-file during runtime. That way you can get all the data available in cTrader. Then you order and interpret them in the best program there is on the market for jugling with numbers: Excel.

Just help the poor bugger

As not every trader is a potential programmer, let's just help marafi5: First put this method just beneath the OnTick(){ } method.

private void closeWhenPos()
        {
            double profit = 0;

            // first make a sum of all the open trades' profits
            foreach (Position p in Account.Positions)
                profit += p.GrossProfit;

            // when profit is negative, we're done
            if (profit <= 0)
                return;

            // otherwise profit > 0 so close all pending orders
            foreach (PendingOrder o in Account.PendingOrders)
                Trade.DeletePendingOrder(o);

            // then stop the robot
            Stop();
        }

Then put the line closeWhenPos(); into you ontick method.

protected override void OnTick()
        {
            closeWhenPos();
        }

Start the Robot on whatever pair you want - the pair does not matter in this case - and as soon as the total profit of open positions > 0, the pending orders will be closed. That could be immediate, or after hours of waiting.

I use a similar bot to close all positions when my daily (or weekly) target is met:

private void closeWhenTarget(double target)
        {
            double profit = 0;

            // first make a sum of all the open trades' profits
            foreach (Position p in Account.Positions)
                profit += p.GrossProfit;

            // when profit is negative, we're done
            if (profit < target)
                return;

            // otherwise profit > 0 so close all pending orders
            foreach (PendingOrder o in Account.PendingOrders)
                Trade.DeletePendingOrder(o);

            // and close all open positions
            foreach (Position p in Account.Positions)
                Trade.Close(p);

            // then stop the robot
            Stop();
        }

Where the variable target is set by a parameter.

Hoped this helps you out on your quest.

Thanks and ready it is

Spotware said:

The candle is made of the Bid price.

Thanks for the quick response. In that case my indicator is ready. Don't know what it's good for, but it does show information that used to be hidden in the candle. I'll upload it somewhere.
