I'm a prop trader in Swift Trade, but just for 2 months. My boss doesn't allow me to trade derivatives. But derivatives is my favorite subject anyway. So I want to learn sth from anyone here...... Do prop traders perform option strategies which can be seen ordinarily in textbooks? Such as bull/bear spread, butterfly, condor, straddle, strangle.....etc. Do these strategies have to be hold for a longer time period, like several weeks or even months? Are they useless in day trading? And may you tell any other possible trading strategies about option? Thanks.
