I thought I explained myself clearly before, obviously not.
No one is aware of a program to enhance Tradestation order entry.
That was the QUESTION .
No one has answered that question YES.
Thats all I wanted to know.

Tradestation can put a "ShowMe" when a certain condition happens at a
certain point on the bar, not just open, close , high, or low.
Tradestation can generate an Order to Exit a trade (Sell/Buy to Cover) at a
certain price based on indicator variables , not just at open, close, or
market.
So why not a Order entry.

Several MESSY ways around the problem especially if your using tick charts.

I don't insist , I just asked.
And I asked because
1. I'm using tick charts which cant use multiple data streams on the same
chart.
2. I'm using multiple timeframes. (Tick Fames)
4. I'm using multiple indicators.
3. Because of all those reason you pointed out in your email about how messy
it is to work around this limitation of Tradestation.
