Now my problem is I bought 1 lot of US100 then I close partial volume using this code

double volume = 0.5;ModifyVolume(volume)

it says Bad Volume.

But when I close .5 lot using a normal close, I mean not using a bot, it accepted it.

 

Post your code. For all I know, your code could have done something else, or reduced the size already before, or you could be using the wrong position or something else.

The code is below.
To replicate, you have to buy 1 lot of US100 (Nasdaq).

 

using System;using System.Linq;using cAlgo.API;namespace cAlgo.Robots{    [Robot(AccessRights = AccessRights.None, AddIndicators = true)]    public class TestModifyOrder : Robot    {        protected override void OnStart()        {            var position = Positions.FirstOrDefault();            if (position != null)            {                try                {                    double volume = 0.5;                    TradeResult tradeResult = position.ModifyVolume(volume);                    if (tradeResult.IsSuccessful)                    {                        Print("Success!");                    }                    else                    {                        Print($"Error: {tradeResult.Error}");                    }                }                catch (Exception ex)                {                    Print(ex.Message);                }            }        }        protected override void OnTick()        {            // Handle price updates here        }        protected override void OnStop()        {            // Handle cBot stop here        }    }}

Works perfectly for me.

 

I bought 1 lots of NAS, then started the bot:

 

Your statement “var position = Positions.FirstOrDefault();” might not work as you want if you have other positions open at the time because “.first()” may or may not return NAS as the first position in the open positions you have.

I think its a broker related problem then. Im using ICMarkets

RE: Lots vs Units

firemyst said: 

Is lot and unit the same?

Not always. Depends on what you're trading.

For forex pairs, 1 lot = 100,000 units.

Got it!

Now my problem is I bought 1 lot of US100 then I close partial volume using this code

double volume = 0.5;
ModifyVolume(volume)

it says Bad Volume.

But when I close .5 lot using a normal close, I mean not using a bot, it accepted it.

Hi agent.xzxz,

You need to change 

double openPriceByIndex = Bars.OpenPrices.Last(index);

to

 double openPriceByIndex = Bars.OpenPrices[index];

Best Regards,

RE:

Hi,

Can you run this code on your side? Select Monthly Timeframe.

using System;
using cAlgo.API;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class IndexByTimeIssue : Robot
    {
        protected override void OnStart()
        {
            double lastBarOpenPrice = Bars.OpenPrices.LastValue;
            DateTime lastBarOpenTime = Bars.OpenTimes.LastValue;

            int index = Bars.OpenTimes.GetIndexByTime(lastBarOpenTime);

            double openPriceByIndex = Bars.OpenPrices.Last(index);
            Print("Equal?: ", lastBarOpenPrice == openPriceByIndex);
        }

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

        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

Why lastBarOpenPrice is not equal to openPriceByIndex?

I only get the index by time right? They should be equal.
