If you were currently in training at a certain UK prop shop, they would be teaching you order flow by having you perform a number of drills.
This entails SIM trading, with a minimum number of trades per day target & with a certain 'goal'. The goal is not necessarily profit but more style based such as:
"Stay in the market all day. Attempt to be trading in the direction of the market alll day"
or
"Take minimum 75 trades a day with a MAXIMUM 2 tick target on each trade".
I don't have access to the full program but I do know that they do not allow their students to use charts. Note that this prop shop is one that is funding it's traders, NOT asking them for money.
