I currently use TradeStation and do not know much about Ninja. I did a search, and did not find my answer prior to this post.

My question is: Does Ninja have a command that can be used with an automated strategy to hide the number of contracts in resting orders (limit & stop)? TradeStation uses the command SetShowOnly, but I was told by the TS trade desk that it doesn't work with the TS ECN unless you manually enter an order and use the advanced order field "show only".

What I am trying to accomplish is hide the number of TF contracts I have resting with a limit and/or stop order. It has been explained to me that the number of contracts can be set to any number you would like until the order is actually filled and then the real number of contracts is shown.

Thank you for your help.

For stop loss orders, you can keep them locally and send to exchange only once price trades at that level (very risky, but hidden).

As for the rest, yes it can be done - thru advanced custom programming in NinjaScript.
