RE:

i want to check some parameters on each tick and change the period1 from calculate,

would you mind please explain me how to do this task?

firemyst said:

It won't change unless you create a new MovingAverage with the new setting or overwrite the previous one.

So after you change "period1", you should do this again:

param1 = Indicators.MovingAverage(param2, period1, MovingAverageType.Simple);

The Initialize method will only run again if you display the parameters window and change it that way.

If you programmatically change values, then you need to programmatically create new movingaverage objects with those new parameters.

Hi there,

Well that's not what you asked for initially :) Here is an example

var volume = Symbol.NormalizeVolumeInUnits(Balance * Symbol.DynamicLeverage[0].Leverage / AssetConverter.Convert(1, Symbol.BaseAsset, Account.Asset));

Hi there,

Sorry, is the Symbol.VolumeToQuantity() you should be using. My typo.

thanks for your reply and help

unfortunately this one also not working, for example if account balance is 170usd this will return 0.0017,
i need a code that i give it usd amount, then it calculated maximum lot which use all the 170usd margine in order to manage the risk in next steps,
is leverage should consider manualy?

hi there

unfortunately not working:

public static double GetLotPerRisk(Symbol symbol, double riskPercentage, double accountBalance, double stopLossInPips)
        {
            return symbol.QuantityToVolumeInUnits( accountBalance);
        }

for example if i have 170usd in account this function returns 17000000

Does your bot have full access rights?

public class YourBot : Robot

thanks alot, i changed the accessright to fullaccess and that problem solved but unfortunately i get new erro:

09/03/2023 15:36:36.527 | CBot instance [Sample Hotkey Trading, AUDUSD, h1] crashed with error "Crashed in OnStart with SharpDXException: HRESULT: [0x80040154], Module: [SharpDX.DirectInput], ApiCode: [DIERR_DEVICENOTREG/DeviceNotRegistered], Message: Class not registered "

 

 

error refers to this part of code:

 protected override void OnStart()
        {

            
            directInput = new DirectInput();
            var joystickGuid = Guid.Empty;
            foreach (var deviceInstance in directInput.GetDevices(DeviceType.Gamepad, DeviceEnumerationFlags.AllDevices))
            {
                joystickGuid = deviceInstance.InstanceGuid;
            }

            joystick = new Joystick(directInput, joystickGuid);/////////////////////<<<<<<<<<<here is the error
            joystick.Properties.BufferSize = 128;
            joystick. Acquire();

}

Is your "joystickGuid" variable still empty after that for loop? I have not used this library before, but that's what I would check first.

A quick search found this, if you look here, they are searching for DeviceType.Joystick if there is no result for DeviceType.Gamepad

thank you very much for your guide.

the problem solved and i can read the joystick keys in the cbot but one last question, i use onTick to trigger the key press which is not suitable, i want to get trigger as soon as user press any key on the joystick, how can i solve this problem?

Hi again

just one more problem.

i try to use this linePriceValue in for my stoploss:

position.ModifyStopLossPrice(Math.Round(DefaultSTL,Symbol.Digits)); or position.ModifyStopLossPrice(DefaultSTL);

but unfortunately i get the error:

i print the linePriceValue and the printed value is OK but when i try to assign it to my position stoploss i get the error.

Hi,

You can draw an interactive chart trend line and then whenever the user changed it you can use the chart objects updated event.

i just need one line, which could be change by user on the chart, and in the bot side, we can get it's Y and compare with price, the most important point is that user can click and change the position or angle of the line

RE:

Hi Panagiotis 
thanks for reply
i exactly do the same it works in swing trades but my problem is that in scalp trades when we reach the target usually not execute at the point and close in next ticks which maybe lower prices. is there any trick to close position exactly at the trigger tick?

regards

PanagiotisCharalampous said:

Hi yaghouti,

You can use ModifyVolume method to change the position's volume and partially close it at any stage of the execution. So if you want to close 50% of the position, just modify the volume to be half of the initial quantity.

Best Regards,

Panagiotis
