Bars.BarOpened In 3.7
05 Dec 2019, 18:03

Hi cTrader team,

Firstly, great work on the new 3.7! I’m sure many users can’t wait for it to go live.

Currently, I run a cBot for each symbol I trade on the same time frame as I noticed the bar open and close timing (OnBar) on different symbols may differ by a few seconds.

I plan to consolidate all the symbols into a single cBot using bars.BarOpen to monitor and act whenever the symbol I’m trading opens a new bar.

I have studied the symbol.tick sample you have shared.

Could you also share a sample code for bars.BarOpen to monitor BarOpen events for multiple symbols please? Thanks.

Hi eofe,

The bar's open time is taken from the first new tick that will arrive for that bar. This is why you get different opening times.

Regarding sample, I am not sure what do you need exactly but below you can see a very simple example of listening to the BarOpened event

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class BarOpenedExample : Robot
    {
        protected override void OnStart()
        {
            var bars = MarketData.GetBars(TimeFrame.Minute, "GBPUSD");
            bars.BarOpened += Bars_BarOpened;
        }

        private void Bars_BarOpened(BarOpenedEventArgs obj)
        {
            Print("New bar created for " + obj.Bars.SymbolName + " at " + obj.Bars.Last(0).OpenTime);
        }
    }
}

Hi eofe,

Christmas was the target for the Beta :) We cannot give an ETA for release to brokers, it depends on how the Beta testing will go. We will release to brokers as soon as we are confident that 3.7 is stable enough for production environments.

Best Regards,

Panagiotis
