My diary notes and learning

If this will be useful to anyone I will be happy...

Ok....

This is on the start empty template robot (EA) document:

Please keep adding to this as you go - it is in the true spirit of our forum and will help others program for this platform.

Apart from, anything else, you always have a backup copy if you lose all your files in a disastrous event.

Disadvantage for now is that you can use only current chart time frame and currency in Robots (robots can't trade multycurrency).... but in near future will support this options....

Yes my intention is to write all but I am not good writer and also my english this will look more like notes and one day somebody can use notes to write better cAlgo for Dummies ...

Called on each incoming Bar. This method is used by Robots. Izzy..

Code: Select all

        protected override void OnBar()
        {
            // Put your core logic here
        }

Now I will look to others Robots to find useful things and to learn ...

I find one useful money management function and i will tray to use or adopt to my robot...

Code: Select all

        /// <summary>
        /// Volume calculated based on Risk if winning trade otherwise doubled
        /// </summary>
        protected int Volume
        {
            get
            {
                if (profit < 0)
                    // Profit < 0 => Double previous Volume or use MaxVolume
                    return (volume * 2) > MaxVolume ? MaxVolume : volume * 2;

                // profit > 0 => Calculate Volume based on Risk and Pip value
                var risk = (int)(RiskPercent * Account.Balance / 100);
                var volumeOnRisk = (int)(risk * Symbol.Ask / (Symbol.PipSize * StopLoss));
                // round volume to nearest tradable value
                return volumeOnRisk / VolumeIncreament * VolumeIncreament;
            }
        }

        /// <summary>
        /// Max Allowed trade volume 
        /// </summary>
        protected int MaxVolume
        {
            get
            {
                // calculated based on equity and leverage 
                double maxVolume = Account.Equity * Leverage * 100 / 101;
                //round to the nearest tradable value                
                return (int)Math.Truncate(Math.Round(maxVolume) / VolumeIncreament) * VolumeIncreament;
            }
        }

Hey Babalu4u,


I'm not real sure here, but the first section looks like martingaling against a floating loss...

Code: Select all

                if (profit < 0)
                    // Profit < 0 => Double previous Volume or use MaxVolume
                    return (volume * 2) > MaxVolume ? MaxVolume : volume * 2;

Not a nice toy to play with. Might be better to get rid of that bit.

Have fun!

Hi Radar yes I know, this is only copy paste from one martingale sample robot. I will use only part of that code...
