Order Types

Limit Orders vs Trigger Orders

Limit Orders (openbroker limit):

Execute immediately if price is met
Rest on the order book until filled or cancelled
A limit sell BELOW current price fills immediately (taker)
NOT suitable for stop losses

Trigger Orders (openbroker trigger, openbroker tpsl):

Stay dormant until trigger price is reached
Only activate when price hits the trigger level
Proper way to set stop losses and take profits
Won't fill prematurely
