You need to make sure that you use class name instead of indicator name. For instance, you need to use "SampleSMA" instead of "Sample SMA" in example shown there: /api/guides/indicators#el7

There's no extension for SharpDevelop. However you can write a library using SharpDevelop and reference your cBot/Indicator to this library.

RE: RE: RE: RE: RE: RE: RE:

As far as we see from your screenshot in MT4 you have extra candle on weekend day. Trading session in cTrader is configured to end on Friday and to start on Monday.

You should clarify about trading session configuration with your broker.

TonyPro said:

yes, it is. and each tick price is same for mt4 and ctrader , but the daily bar isn't same.

TonyPro said:

The problem is cTrader chart and MT4 chart aren't same for the same trading day. even though I have wrote the same strategy as MT4 using C#, it doesn't work because the difference of two charts. but I know that the datas are same for both of charts. Is there any way to fix it?

Spotware said:

Daily bars start at 17:00 EST and it's not up to cAlgo to change that time.

If you need daily bars to open at 00:00 than you need to specify TimeZone of your cBot. 

using cAlgo.API;

namespace cAlgo
{
    [Robot(TimeZone = TimeZones.EEuropeStandardTime, AccessRights = AccessRights.None)]
    public class BarOpen : Robot
    {
        protected override void OnStart()
        {
            Print(MarketSeries.OpenTime.LastValue);
        }
    }
}

will give you: 21.07.2014 0:00:00

Can I set the daily bars start time to 00:00 EST? because my strategy is based on that time.

Spotware said:

Daily bars are aggregated by 17:00 EST which is equal to 21:00 UTC. That's why you see such results.

I want to backtest daily data during 2013 ~2014, but the problem is after I point the cursor to one daily bar, the daily info at the bottom bar is wrong. Specifically, the open time start from 21:00, and the open price is 21:00 hour open price, instead of daily open price. but the chart I'm using is daily chart, is this a bug of cTrader?

RE:

DateTime.Today returns System current time. You need Server.Time

flannery said:

Hey,

So I have been working on a bot where I need to get the price on the forex cross at specific times. This is not a problem when working with realtime. A snippet of what I have used for that part:

string day_0 = DateTime.Today.AddDays(0).ToString("dd/MM/yyyy");
..
cAlgo.API.Internals.MarketSeries barSeries = MarketData.GetSeries(TimeFrame.Minute15);
..
barSer_08 = barSeries.OpenTime.GetIndexByExactTime(DateTime.Parse(day_0 + " 8:00AM"));    double History_Price_08 = MarketSeries.Open[barSer_08];

Now this will give me the open price of the bar at the exact time: today (bot is running after the time that day) at 8 AM.

 

However, when I try to use the same bot for historical testing it will not get the price of the "day today" for each day in the historical test.

Is it possible to do this with the historical tester?

RE:

Hi clydeboo.

You have to pass data series of indicator: slowMa.Result

protected override void OnStart()
{
    slowMa = Indicators.MovingAverage(OpenSourceSeries, SlowPeriods, MAType);
    fastMa = Indicators.MovingAverage(OpenSourceSeries, FastPeriods, MAType);

    vidya = Indicators.Vidya(slowMa.Result, vidPeriod, vidSigma);
}

Just want to start off by saying that cAlgo rocks! Hats off to all the developers. cAlgo is a traders wet dream. Unfortunately this is a point of frustration with me because I'm not up to speed with cBot construction and the unbelievable potential continues to stare me in the face.

I've developed a bot that I'm incredible happy with but it needs refinement  I want to develop more error management to minimize poor entry and or correct direction. This process has led me to using nested indicators. I want to create a VIDYA data series that uses a Welles Wilder Smoothing data series as its data source. I see how it is done when building an indicator but not how to do it with a bot. 

I'm sure the process is simple...I just need a little nudge in the right direction.

        public int vidPeriod { get; set; }

        [Parameter("VIDYA Sigma", DefaultValue = 0.65, MinValue = 0.1, MaxValue = 0.95)]

one is via stop loss parameter 

You set the stoploss on executing market order. So no extra actions needed there.

 ExecuteMarketOrder(TradeType.Buy, Symbol, Volume, "calgoo", StopLossInPips, TakeProfitInPips);

 

other by value of ask price against EMA is it possible to do so? if yes how to?

        protected override void OnTick()
        {
            CheckForEMA();

For the above example if OnTick handler takes 5 seconds to process 1 tick while several ticks come to the platform, next OnTick handler will be invoked for the latest unhandled tick. All previous ticks will be skipped.

You may also be interested in newly added RefreshData method. It explicitly updates MarketSeries, Positions, PendingOrders, etc.

It looks like antivirus or local network configuration does not work correctly with technology, we use to communicate with servers (web sockets).

Try to disable antivirus, if you have one.

You may use this website http://websocketstest.com to diagnose if web sockets work for you. Anyway, if it says, that web sockets work, your company firewall may have such rules, that only affect particular addresses. Talk to admins, try VPN (this might work).
