I have been constantly testing and searching for a signal to get me in the trade between level 3 and level 4 without waiting for price to hit level 3 again.
Such a signal would be very useful when the spread between level3 and level4 is larger than normal.

If we could get a fairly accurate signal that would work on a 5 or 15 minute chart I believe that would be ideal for being able to correctly enter the trade early....Will keep trying and keep you posted
