How can I make sure trades happen only one per bar?

[tkaboris]

HI i havea a strategy oneachTick. How can I make sure orders are only open one per bar.
I have
(Position.MarketPosition == MarketPosition.Flat) &&
(BarsSinceExitExecution("MyStopLong") > 1 || BarsSinceExitExecution("MyStopLong") == -1)

You need to save this in a variable. A potential problem with OnEachTick is that it takes a bit to get an execution so BarsSinceExecution isn't updated and in the meantime you are sending order after order after order. But, another approach would be if these are managed orders and you are not scaling in, set EntriesPerDirection to 1. If you are scaling in, set EntryHandling to EntryHandling.UniqueEntries and set EntriesPerDirection to 1 and give each "scale-in" part a different entry name.

Hello tkaboris,

Thank you for your post.

I see within BarsSinceExitExecution you are using the signal name "MyStopLong" - does this match one of the signal names used in your strategy? Based on your screenshot, I see "SL" and "2EL" though I am not seeing a signal name of "MyStopLong" so this could potentially be the issue.

Otherwise, since you want only one entry per bar, you could try using a bool that gets set to false when an entry has been submitted for that bar, then it gets set back to true on the first tick of the next bar. For example:

if (IsFirstTickOfBar && allowEntry == false)
allowEntry = true;

if (Position.MarketPosition == MarketPosition.Flat && allowEntry = true)
{
// entry order here
allowEntry = false;
}

Please let me know if I may be of further assistance.

HI
I have wrote this for Longs since. Would this be correct then?

&& (BarsSinceExitExecution("SLL") > 1 || BarsSinceExitExecution("SLL") == -1)
&& (BarsSinceExitExecution("PTL") > 1 || BarsSinceExitExecution("PTL") == -1)

ExitLongStopMarket(0, true, Position.Quantity, StopLossTicks, "SLL", "2EL");

ExitLongLimit(0, true, Position.Quantity, Position.AveragePrice + (TickSize * ProfitTargetTicks), "PTL", "2EL");

Hello tkaboris,

Thank you for your reply.

Just based on your snippet out of context, I am not sure if this will result in your desired behavior. You will ultimately need to test your strategy to observe and understand its behavior. What I can see is you are using the signal names from your exit orders ("SLL" and "PTL") in your condition that checks BarsSinceExitExecution which does appear to be correct. As mentioned in the help guide page for BarsSinceExitExecution(), the signalName should be the signal name of an exit order specified in an order exit method:
