I need an indicator that can help me to create an EA. The mentality is: there are 3 five minute bars to form a 15m bar, I want to make a long trade at the beginning of the next 15m bar when the 2nd 5 minute bar's close price is higher than the open price (white bar).

The conditions:
The 1st 5 minute bar (in the previous 15 minutes) is a white bar
The 2nd 5 minute bar is a white bar (close higher than the open)
The 3rd 5 minute bar is a white bar
The 1st 5 minute bar is a black bar
The 2nd 5 minute bar is a black bar
The 3rd 5 minute bar is a black bar

Can anybody create this indicator for me? Many thanks
