Help for pyramiding in Tradestation

Hello all!

This is my first post here. Be patient with my English!

I'm searching listing or example of scaling strategy in EasyLanguage for Tradestation.
I found that TS isn't so flexible for this strategy...

I need entry one time, reentry if price decline and exit with scale out on profit level.
The problem is that EntryPrice function in some situation don't return the real entry price!

Can someone help me with link to example of pyramiding with scaling in and scaling out?

Thank to expert!

Ciao
