Dynamic order size

[mitnick_d]

Hello,

Can you please tell me if the order size of a certain strategy can be modified according to what happened in the previous trades?

Let me give an example to make myself more clear:

standard order quantity 10.000 units

if at the last 2 trades the stop loss was hit, for the third trade I would like that the quantity to be smaller with 20% (8.000 units).

Can it be done?

Yes this can be done. You would need to use your own tracking variable for quantity but you can use the following as a good example for tracking performance

Along with looking at the above example, I'd suggest also looking at the help guide links in the post as well.

Let me know if I can further assist.

Unfortunately, I am not much of a coder... For example purposes I placed the orders on a simple MA cross strategy

I set some conditions, but:

1. it executes only the last one ( EnterShort(100000, "") )
2. what condition should I use in order for the strategy to use only the most recent consecutive losses

Thank you in advance!

protected override void OnBarUpdate()
{
// Condition set 1
if (CrossBelow(SMA(5), SMA(14), 1))


if(Performance.AllTrades.TradesPerformance.MaxCons ecLoser > 4);
if(Performance.AllTrades.TradesPerformance.GrossLo ss > 601);
if(Performance.AllTrades.TradesPerformance.GrossLo ss < 700);
{
EnterShort(70000, "");
}

if(Performance.AllTrades.TradesPerformance.MaxCons ecLoser > 3);
if(Performance.AllTrades.TradesPerformance.GrossLo ss > 500);
if(Performance.AllTrades.TradesPerformance.GrossLo ss < 600);
{
EnterShort(80000, "");
}


if(Performance.AllTrades.TradesPerformance.MaxCons ecLoser > 2);
if(Performance.AllTrades.TradesPerformance.GrossLo ss > 301);
if(Performance.AllTrades.TradesPerformance.GrossLo ss < 400);
{
EnterShort(90000, "");
}

{
EnterShort(100000, "");
}


}

Hello Mitnick,

Thank you for your response.

1. The strategy is likely not entering more than once per the EntriesPerDirection setting of 1 (by default).
You can change this in your code with the following:

protected override void Initialize() 
{ 
    EntriesPerDirection = 4;

2. There is no method to pull the most recent consecutive losers, you will need create your own logic to manage this using the Trade Collection values at the following link: http://www.ninjatrader.com/support/h...collection.htm

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

I ordered it to a developer and solved the case.

Thank you Lance and Patrick for your support!
