Update order

[malcolm]

If I enter a limit order (in a strategy) and want to update the price, do I need to have assigned a name to the order? How do I do that and are there any examples to view?

Hello malcolm,

Thanks for your post.

No, you do not need a name. If a limit order has not yet been filled and you submit a limit order at a different price, the price will be adjusted.

Here is a quick example to demonstrate:

if ((State == State.Realtime)
&& (Doitonce == true)) // Doitonce is a bool that is initially set to true
{
EnterLongLimit(Convert.ToInt32(DefaultQuantity), (Low[0] + (-10 * TickSize)) , ""); // this is the initial order 10 ticks below the low of the just closed bar, done once
Doitonce = false;
}

// Set 2
if (Doitonce == false)
{
EnterLongLimit(Convert.ToInt32(DefaultQuantity), (Low[0] + (-20 * TickSize)) , ""); // This adjusts the same order to 20 ticks below the low and will be different price on each new bar
}


Note: If you did use a signal name you would need to use the same signal name to update the same order. Same example but with a signal name:

if ((State == State.Realtime)
&& (Doitonce == true)) // Doitonce is a bool that is initially set to true
{
EnterLongLimit(Convert.ToInt32(DefaultQuantity), (Low[0] + (-10 * TickSize)) , "Test"); // this is the initial order 10 ticks below the low of the just closed bar, done once
Doitonce = false;
}

// Set 2
if (Doitonce == false)
{
EnterLongLimit(Convert.ToInt32(DefaultQuantity), (Low[0] + (-20 * TickSize)) , "Test"); // This adjusts the same order to 20 ticks below the low and will be different price on each new bar
}
