Print just once

[Impeesa]

Hello

I have wrote an strategy that runs OnEachTick. It has a BreakEven condition that works perfect, but I would like just print in output window one line when stop moves to BE. Actually it does since position is opened.

if (BarsInProgress == 0)
&& Condition 1
&& Condition 2

ChangeOrder(stopLongOrder, stopLongOrder.Quantity, 0, Position.AveragePrice);
Print(Time[0] + " || " + Name + " || " + Account + " || " + Instrument);



How can I do it?

Thanks in advanced

Hello Impeesa,

Thank you for the post.

From the given code you would need to add curly braces so that your if condition can execute both commands:

if(....)
{
    //all logic that should apply to this if condition
}

I look forward to being of further assistance.

Hello Jesse

Curly braces were added and obviously just changes order once, but prints lines every tick until position is closed.

if (BarsInProgress == 0)
&& Condition 1
&& Condition 2
{
ChangeOrder(stopLongOrder, stopLongOrder.Quantity, 0, Position.AveragePrice);
Print(Time[0] + " || " + Name + " || " + Account + " || " + Instrument);
}

Any other option?

Hello Impeesa,

If the condition remains true the print would keep happening, is that what you are seeing happen here?

If thats the case you would likely need to add a bool to know when to print. For example:

private bool printOnce = false;

later in OnBarUpdate:

if (BarsInProgress == 0)
&& Condition 1
&& Condition 2
{
ChangeOrder(stopLongOrder, stopLongOrder.Quantity, 0, Position.AveragePrice);
if(!printOnce)
{
     Print(Time[0] + " || " + Name + " || " + Account + " || " + Instrument);
     printOnce = true;
}
}

You would otherwise need to make the condition happen less frequently to avoid printing on each tick. The variable would also need reset at some point when the print should be available again, possibly from OnPositionUpdate or just in a condition checking the position is flat.


I look forward to being of further assistance.

Hello, Jesse

Your example is perfect and it would be useful in other purposes. Of course, it works fine in my code.

Thanks a lot
