Trading: The one and only profitable entry at the 50% level

Whats important is to look for a the market to turn higher at 50% of prior swing to go long
or to turn lower at 50% of prior swing to go short. The risk is always the range of the entry bar so the smaller the entry bar the better. Target should be either the 50% level of the current day or a double top bottom or the standard 4 times average true range trailing on a 3 min chart.
