Hi hungtonydang,

You could try something like the following. You can record the time of the last executed order and then check if 24 hours have passed from the last order or not

        protected override void OnBar()
        {
            if (_lastExecutedOrder.AddHours(24) < DateTime.Now)
            {
                ExecuteMarketOrder(TradeType.Buy, Symbol, 1000);
                _lastExecutedOrder = DateTime.Now;
            }
        }

Best Regards,

cTrader Team

I am trying the above code however I get the following error

Error CS0103: The name '_lastExecutedOrder' does not exist in the current context

I am guessing that _lastExecutedOrder needs to be declared as a variable before it can be used. Can anyone help me with the right syntax for the declaration.

Hi Ctrader team,

I found my answer to that problem it has to do with absolute price compared with what the statement accepts. I have found a work around and will try that later.

But it brings me back to my original query of passing indicator values to a cbot.

If we can define absolute values as variables are they not able to be used as a limit or stop order entry price? As we can't use absolute values for stop loss and target profit is this the same? If not please point me in the direction of a sample as I am close to completing my cbot.

Thsnks,

Tony

I am trying to use an indicator value as a Stop loss value however on backtesting the value of the SL looks like it is simply the spread. I have declared the variable is there something else that I am missing?

        protected override void OnBar()
        {
            var SL = BB.Main.LastValue;
            var volumeInUnits = Symbol.QuantityToVolume(Quantity);
                    if (Positions.Count == 1)
                    {
                      Stop();                   
                    }

                    else if (Symbol.Ask > BollingBands.Top)
                    {
                        ExecuteMarketOrder(TradeType.Buy, Symbol, volumeInUnits, label, SL, TakeProfitInPips);
                    }

Any help would be appreciated.

Hi there, I have the same situation but was wondering what is coding best practices to do. Is it better to refer to another modifier like above or use goto statements and split the program inside the onbar? Or does it even matter because the result should be the same. I am looking at implementing a take profit clause that happens onbar action which also executes orders to enter the market if that helps understanding.

Ok I have this working now but it is not working as expected. I am guessing that it might have something to do with the nested if functions that open an order after the delay. 

Is there anywhere I can see some examples of nested if functions on async bots? Or does anyone have sample lines of code they could share please?

I am trying to get the market entry parameters to follow the if statement after the delay has been taken into effect but under the async operation it goes through the code and assigns new entries on the condition being false.

Any help or sample is much appreciated

Thanks for that, must have overlooked that when I was searching. Will try that piece of code tonight.

I found a bit of C# code that might be able to do what I need however it is coming up with errors once I hit the build button. Any help is much appreciated.

        protected override void OnBar()
        {
            if (true == true)
            {
                var volumeInUnits = Symbol.QuantityToVolume(Quantity);
                {
                    if (Positions.Count == 1)
                    {
                        await Task.Delay(TimeSpan.FromHours(8));
                    }

That is my sample code, it says the name Task does not exist in the current context and consider changing to async method.

Is there no way to set an expiration on a timer? I have a bot that changes with an onbar action and so would like to have a limit order only hang around for 1 hr as that is the instance I am using. Can we call on a timer?

I would like to know about expiries on limit and stop orders

            PlaceLimitOrder(TradeType, Symbol, Volume, targetPrice, MyLabel, 
                             StopLossPips, TakeProfitPips, Expiration);

If I understand it correctly Expiration comes last and what is exacrtly the frame of calculation hours or minutes?

Say I wanted a limit order to have a 1hr expiry would the code be

            PlaceLimitOrder(TradeType, Symbol, Volume, targetPrice, MyLabel, 
                             StopLossPips, TakeProfitPips, 1);

or 

            PlaceLimitOrder(TradeType, Symbol, Volume, targetPrice, MyLabel, 
                             StopLossPips, TakeProfitPips, 60);

or do we declare it as a variable?

I am trying to get the bot to execute 1 trade every say 24 hours. So therefore I would like to pause the onbar logic from opening further positions after the first one has been closed rather than stop the whole bot as I would normally be asleep by the time the bot is running.

Ok I have an idea but just wanted thoughts on it.

If I use the above code and specify less than 1 position that should only allow the one position from opening. Then if I make an OnPositionClosed to sleep the robot for the next 12 hours, would that work? or can I use the OnPositionOpen, but then would that cancel my stop and take profit orders?

Sample below I hope I have my numbers and symbols right

protected override void OnBar()
{
    if (Positions.Count < 1)
    {
        // Execute your logic here
    }
}

protect override void OnPositionOpen()
{
int milliseconds = 120000000;
System.Threading.Thread.Sleep(milliseconds);
}

Thanks for the prompt response I will try that later. 

I am after some logic that would also restrict the onbar logic to have 1 trade per wave per se which is normally after about 6 bars. 

At the moment my onbar logic opens new trades concurrently one bar after another until the logic fails. I would like to have one trade overall as the subsequent trades tend to hit sl where as the initial hit tp.

Any help is much appreciated.

After further interaction with the software and code, am I to understand that the indicator is to be called upon at start up of the calgo then the levels have to be calculated then we can say place a limit order at defined level? Can the last 2 be placed under the same function or do they have to be separate? It would also be good if you had a reference code in that forum that people could use. For example to place a limit or stop trade at the level determined by pivot point indicator or even simpler level of a Bollinger band.

Thanks for the link, I have read that page already, I think I understand the logic. Is there a syntax library anywhere with definitions? As that would be really helpful with what I have in mind.
