Is there a way to break up a large order into a blast of smaller orders on NinjaTrader? Their ATM appears to be all-in/scale-out construct based on different price levels. But I'm talking about, say, if you want to go long 200 contracts of something at such-and-such a price, it'll break it up into, say, 10 separate orders. Anyone? Thanks

A common technique used by discretionary traders is scaling in and scaling out of a position. To scale out of a position refers to closing a portion of your position when you hit a profit target and then raising your stop to close your remaining portion later.

Key concepts in this example:
Submitting Profit Target orders
Submitting Trailing Stop orders
Closing half of your position at a time

Thanks for the response. I'm looking to scale in as well as scale out. Is this not really doable on NinjaTrader?

It's very doable but will require custom coding for the scale in.
What you want is a strategy so if you're able to describe it (how many lots, when add another lot, stop/profit for each lot or a global one, etc.) it's doable.

Where can a person learn this in a non intimidating or easily digested way?
