Having trouble with EnterLongLimit()

[Xiongl80]

It seems my limit price keeps moving, most likely along with the actual ask/bid price. For my code below, my strategy shows numerous canceled orders and the entry won't execute. The canceled orders are around the time that my if statements are being satisified. Any ideas?

CalculateOnBarClose = false;

if (entry requirements here)
{
EnterLongLimit(DefaultQuantity, Close[0] + 1, "Long Entry One");

if (profit loss requirements here)
{
SetStopLoss(CalculationMode.Ticks, 12);
}
}

My reasoning is that with CalculateOnBarClose = false, my Close[0] price is moving along with the current price since the strategy updates tick-by-tick, and each time it updates and satisfies the if statements, then another long limit is entered at a different Close[0] price. However, I thought my Close[0] price should have been the close of the last bar, which is unchanging. Please let me know if this could be the case and how I can fix it.

Thanks,

Lee,

When you use EnterLongLimit() with that signature it will auto expire on every bar if you do not resubmit the order to keep it alive. This means that if your conditional if-statement is no longer true the order would be expired and cancelled. To prevent this you can either reprogram the logic to have the if-statement true throughout the entire life of the order, or you can use the signature for EnterLongLimit() that uses liveUntilCancelled set to true.

EnterLongLimit(int barsInProgressIndex, bool liveUntilCancelled, int quantity, double limitPrice, string signalName)

I understand setting LiveUntilCanceled to true and then using a CancelOrder() when I want the order canceled, but could you explain in detail what you mean by reprogramming the logic to have the if-statement true throughout the entire life of the order? Or maybe you can provide a very simple code as an example of what you mean?

For example, if my condition was something like this:

if (CrossAbove(SMA(10), SMA(20), 1))
     EnterLongLimit(...);

You can see that a cross over condition would only be true on 1 bar. This becomes a problem if we wanted the limit order to be kept in the market until it gets filled or otherwise cancelled. The very next bar this order would be expired if we left it alone like this.

Now consider this approach:

if (keepAlive == false && CrossAbove(SMA(10), SMA(20), 1))
{
     EnterLongLimit(...);
     keepAlive = true;
}
else if (keepAlive)
     EnterLongLimit(...);

The order is resubmitted regardless of the original cross over condition and therefore kept alive. All you need to complete this approach would be to designate a condition (if desired) to set keepAlive to false and then the order would auto expire afterwards.
