Indeed, Last(0) is as fast as Last(1) but since Last() does compile and also seems to deliver the same result (only much slower) I wonder why this has not been handled in code.

Anyway, I hope my post here will help others facing the same issue.

would be nice to see on the chart my past activity

Right click in the chart area, select "Viewing Options" and activate "Deal Map". Is that what you are looking for?

Hypothetically what you could do is:

//To find a bearish fractal in a range:
int startIndex = 4;
int endIndex = 7;
array.Skip(startIndex).Take(endIndex - startIndex).Max();

And see if the middle value of the array is equal the max value returned. If so, it's a bearish fractal.

note that according to the definition of a bearish fractal is as follows from Investopedia:

• A bearish turning point occurs when there is a pattern with the highest high in the middle and two lower highs on each side.

   

It doesn't say each high has to be lower/higher than the previous/next. Only that the one in the middle has to be the highest/lowest. So given that interepretation, you could use the sample code I put in at the top here.

If you do want it with each candle getting consecutively higher/lower from the middle one, I don't know how you do that without looping over each value.

Thanks a lot! I will give it a try. Actually my current implementation only checks whether the bar in the middle is the same, as the highest value of the whole range. Which leaves the option that there are other bars with the same value.

What you should try doing is looking at how others have done it, and adapt your code as appropriate.

For example:

 

 

Hi, thanks for your message. Of course I checked for other implementations and also had a look at your example. That is what I meant by "The only other implementation would be to iterate over each bar and check manually whether it is higher than the price of the bar in the middle of my range". I was curious if someone here found another way...

Hi, 

The volume for gold is typically not provided in lots. Depends on your settings in cTrader. If you check the logs of your bachtest you will see, that your lot size is always 0 and therefore rejected by the Market Order function.

But there is a better way to calculate the volume for your bot. See the amended code below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using cAlgo.API;
using cAlgo.API.Collections;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.None)]
    public class StochasticTest : Robot
    {
        // Order Parameters
        [Parameter("Session", DefaultValue = MarketSession.London)]
        public MarketSession MarketSession { get; set; }

        [Parameter("Take Profit", Group = "Order", DefaultValue = 500, MinValue = 100, Step = 10)]
        public int TakeProfit { get; set; }

        [Parameter("Stop Loss", Group = "Order", DefaultValue = 80, MinValue = 80, Step = 10)]
        public int StopLoss { get; set; }

        [Parameter("Risk (%)", Group = "Order", DefaultValue = 2, MinValue = 0.01, MaxValue = 5, Step = 0.01)]
        public double RiskOfBalance { get; set; }

        // Stochastic parameters
        [Parameter("Fast K% Period", Group = "Stochastic", DefaultValue = 5, MinValue = 2, Step = 1)]
        public int FastKPeriod { get; set; }

        [Parameter("Slow K% Period", Group = "Stochastic", DefaultValue = 3, MinValue = 2, Step = 1)]
        public int SlowKPeriod { get; set; }

        [Parameter("%D Smoothing", Group = "Stochastic", DefaultValue = 3, MinValue = 2, Step = 1)]
        public int DSmoothing { get; set; }

        [Parameter("MA Type", Group = "Stochastic", DefaultValue = MovingAverageType.Simple)]
        public MovingAverageType StochMovingAverageType { get; set; }


        private double StartingBalance;
        private StochasticOscillator StochasticIndicator;
        

        protected override void OnStart()
        {
            StartingBalance = Account.Balance;

            StochasticIndicator =
                Indicators.StochasticOscillator(FastKPeriod, SlowKPeriod, DSmoothing, StochMovingAverageType);


        }

        protected override void OnBar()
        {
            Open(TradeType.Buy);
        }

        protected override void OnStop()
        {
            // Handle cBot stop here
        }

        private void Open(TradeType tradeType)
        {
            double volume = Symbol.VolumeForProportionalRisk(ProportionalAmountType.Balance, RiskOfBalance, StopLoss);

            if (Positions.Count < 1)
            {
                Print($"Opening buy position on {SymbolName} for {volume} volume.");
                ExecuteMarketOrder(tradeType, SymbolName, volume, "comment", StopLoss, TakeProfit);
            }
        }
    }
}

Detach Ctrader-CLI from Ctrader-Desktop and use web assembly along with Ctrader-WEB to enable Ctrader-Automate (cBots and custom indicators) to work on other Operating Systems.

This sounds to me like a suggestion. Better move it there...

PS: I like the idea!

With version 4.7.13 this issue seems to be gone. Now it works fine for USD pairs.

Hi,

I am using of one of the sample cBots provided, added a currency pair and change the quantity parameter by using the up and down arrows of the input field. But instead of increasing or decreasingg the value by 0.01 the value is increased by 0.1.

As soon as I change the code and use a Step=0.15 it respects the second digit and changes the value by 0.15.

Am I the only one experiencing this behaviour?

Example code take from SampleBreakoutcBot:

[Parameter("Quantity (Lots)", Group = "Volume", DefaultValue = 1, MinValue = 0.01, Step = 0.01)]
public double Quantity { get; set; }

 

I installed latest version 4.7.11 of cTrader Desktop for Windows and now it is working properly.

I did once more a clean installation, but it seems to me, the problem is not really solved by that. I have a video which shows how the functions work for one currency pair but not for another pair. So at the moment I can run my test bot successfully with EURGBP on 1H, but when switiching to EURUSD on 1H the functions always return 0. The video is 144 MB big. Not sure how to provide it to you.

After I did the clean installation EURGBP was the first test I run and it was successful. Then I change my language settings from German to English and run the test with EURUSD and now the issue occurred. Swittching back to English does not change anything, nor deleting local data under App\Roaming\Spotware. 

My best guess is that the issue is relatedt to the bars data downloaded. Not sure if a change of language settings may have an impact on data formats.

I also made a test with a different broker (an old FTMO account) but no difference there. 

I should mention that I run cTrader on Windows 10 on an Apple Macbook Pro (Intel) with Bootcamp.

Please let me know what additional information I can provide to support further analysis.

Thanks in advance

Hi there,

I tried it but there is no noticeable difference for me. Can provide more information i.e. broker and backtesting settings, and maybe record a video demonstrating this difference?

I will create a video, but now I have the first issue again and need to solve this again. :-(

My broker is fpmarkets.com and I used EURGBD on 1H with tick data for last 30 days as backtesting settings.

Thanks for the quick response. The clean installation solved my problem. 

Now the bot takes several seconds to finish backtesting even so it doesn’t do anything in OnTick or OnBar. 

When I remove the Symbol function calls in OnStart it runs as fast as expected. 

Any idea what this could be the reason?
