asian range low or london open low to london close high

If price forms a asian range low for the next day and london close does a daily high. i will place my fib on either 00 20 50 80 levels of the asian day low and 00 20 50 80 on the london close high. wait for price to get to my fib ote area and take a long position. Same goes if london does a daily low for the day and goes to either a new york kz high or london close high.

If prices does a asian range low but goes up to a new york open killzone high. i will not take that trade. My back tests have proven a higher failure rate doing that.

All that said. This is only if the daily bias is looking for a buy. I am not trading this if this is a bearish market.
