Automated process using EZL what would be the command to accomplish the order?

Hello Traders

I am building an automated process using EZL,

I want to be able to execute my order when the condition become true within the bar.
I have set my signal with [IntraBarOrderGeneration = True]

from everything I have read, I have to either write a command
this bar at close or next bar at open.

EXAMPLE:
If Market Price=1995 and is less than SOPEN=2000, and The Market Price Crosses_Over SOPEN at 2000
I want to buy the "Long Order" @ 2000, when the condition becomes true

CODE:
If Price < SOPEN and Price Crosses over SOPEN then
Buy("Long Entry) {what would be the command}

What would be the command to accomplish the order?
