You don't need get set for variables,try this one instead:

private DEMA Dema;
private TEMA Tema;

I'd like to see the DEMA and TEMA code if the code above doesn't work.

Also the last error is just telling you that there is a newer API that does the same thing.

You can simply replace QuantityToVolume with QuantityToVolumeInUnits.

Thanks for your reply,that didnt work,this is the code for DEMA:

using System;
using cAlgo.API;
using cAlgo.API.Indicators;
 
namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, AccessRights = AccessRights.None)]
    public class DEMA : Indicator
    {
        [Parameter]
        public DataSeries DataSource { get; set; }
         
        [Output("DEMA",Color = Colors.Yellow)]
        public IndicatorDataSeries dema { get; set; }
 
        [Parameter(DefaultValue = 14)]
        public int Period { get; set; }
 
        private ExponentialMovingAverage ema;
        private ExponentialMovingAverage ema2;
         
        protected override void Initialize()
        {
            ema = Indicators.ExponentialMovingAverage(DataSource,Period);//i need the correct DataSeries
            ema2 = Indicators.ExponentialMovingAverage(ema.Result,Period);
        }
         
        public override void Calculate(int index)
        {
           dema[index] = (2* ema.Result[index] - ema2.Result[index]);
        }
    }

and this is for TEMA:

using System;
using cAlgo.API;
using cAlgo.API.Indicators;
 
namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, AccessRights = AccessRights.None)]
    public class TEMA : Indicator
    {
        [Output("TEMA")]
        public IndicatorDataSeries tema { get; set; }
         
        [Parameter("Data Source")]
        public DataSeries DataSource { get; set; }
 
        [Parameter(DefaultValue = 14)]
        public int Period { get; set; }
 
        private ExponentialMovingAverage ema1;
        private ExponentialMovingAverage ema2;
        private ExponentialMovingAverage ema3;
     
        protected override void Initialize()
        {
            ema1 = Indicators.ExponentialMovingAverage(DataSource,Period);
            ema2 = Indicators.ExponentialMovingAverage(ema1.Result,Period);
            ema3 = Indicators.ExponentialMovingAverage(ema2.Result,Period);
        }
         
        public override void Calculate(int index)
        {
            tema[index] = 3*ema1.Result[index] - 3*ema2.Result[index] + ema3.Result[index];
        }
    }

and if I replace replace QuantityToVolume with QuantityToVolumeInUnits I get this Error:

Error CS0266: Cannot implicitly convert type 'double' to 'long'. An explicit conversion exists (are you missing a cast?)

and by the way I havent write the code for this two indicator, TEMA & DEMA cods are for user

Thanks a lot man :) you just made my day,it works now

I did some backtest and optimization but the results were not great,then I changed it into two different Dema instead of Tema&Dema and the results were better,but I need to Add one more indicator to filter out the false signals and I think AdxVma is the right choise, this way when market is flat bot wont open a position.

This is the code for AdxVma:

using System;
using cAlgo.API;
 
namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, AccessRights = AccessRights.None)]
    public class AdxVma : Indicator

        }
    }
}

But now I have an other problem adding this code to my bot, I want the logic be like  if AdxVma wasent flat open a position but this dosent work and I know mainly because my lack of knowledge in c# :( 

this is the new code:
