" am trying to make this cbot open trades exactly on the MA crossing"

This depends on when you define a MA crossing. Right now, your code doesn't check the current bar/candle to see if the MA's crossed. Rather, it checks the previous bar and the bar before that (last(1) and last(2)).

If you want it on the exact tick that it happens, then you need to check the current values of the MA against the previous bar's values. Eg, last(0) and last(1) instead of last(1) and last(2).

Thanks firemyst

i don't know how i missed that, regards it worked if you were a girl i would have kissed you,

thanks

Hi,

Your indicator code has a bug, you access the Last(1) which means there should be at least two bars inside Bars collection two access the last second one, and if it's the first bar then it throws argument out of range exception.

You should check IsLastBar of Index == 0, try this:

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class DailyPriceLines : Indicator
    {
        private Bars _bars;
        
        [Parameter("High", DefaultValue = true)]
        public bool High { get; set; }

        [Parameter("Low", DefaultValue = true)]
        public bool Low { get; set; }

        [Parameter("Open", DefaultValue = true)]
        public bool Open { get; set; }

        [Parameter("Close", DefaultValue = true)]
        public bool Close { get; set; }

        [Parameter("High Color", DefaultValue = "Red")]
        public string HighColor { get; set; }

        [Parameter("Low Color", DefaultValue = "Lime")]
        public string LowColor { get; set; }

        [Parameter("Open Color", DefaultValue = "Transparent")]
        public string OpenColor { get; set; }

        [Parameter("Close Color", DefaultValue = "Transparent")]
        public string CloseColor { get; set; }



        protected override void Initialize()
        {
            _bars = MarketData.GetBars(TimeFrame.Daily);
        }

        public override void Calculate(int index)
        {
            // This or index == 0 will fix the issue
            if (!IsLastBar) return;
            
            if (High)
                Chart.DrawHorizontalLine("Daily Heigh", _bars.HighPrices.Last(1), HighColor, 1, LineStyle.Dots);

            if (Low)
                Chart.DrawHorizontalLine("Daily Low", _bars.LowPrices.Last(1), LowColor, 1, LineStyle.Dots);

            if (Open)
                Chart.DrawHorizontalLine("Daily Open", _bars.OpenPrices.Last(1), OpenColor, 1, LineStyle.Dots);

            if (Close)
                Chart.DrawHorizontalLine("Daily Close", _bars.ClosePrices.Last(1), CloseColor, 1, LineStyle.Dots);
        }
    }
}

Aaaah Aaaah it's working thanks bro you the best thumps up

Hi,

I can't reproduce this issue, can you post again the exact code you are using?

On which symbol and time frame you tested it?

Well i've seen something strange, LOOK

BUT ON 1DAY

it's showing on all other timeframe except the 1Day chart which i use for day analysis

Hi,

I just tested on both version 4.1 and 4.2.10 and it works fine:

Does it gets suspended immediately after you attach it or after sometime? which exact version of cTrader 4.2 you are using?

i'd say it's immdiately i attach it to the chart on the current version 4.2.10

it's good thanks

i thought this issue was sorted but i've just realized it was not... the indicator won't update it's stuck, and in some timeframe it's not showing, but when i delete it

it shows's and stay stuck.

Hi,

We were able to reproduce the issue with your indicator, we are investigating now what's causing it, please be patient and wait for our reply.

is there anyway i can downgrade the platform?

Hi,

There is no way to downgrade, for this particular indicator you can comment the "this.ChartObjects.RemoveAllObjects();" line and it will work on version 4.2.

isn't this the same thing already on the indicator or where am i supposed to comment that?
