Pin Bar indicator modification

Hi,

I am attaching a simple Pin bar indicator. I need your help for it's modification.

Here are the rules

For Bullish Pin Bar ( hammer)

1) the low must be less than or equal to mid BB ( 18 , 2 )
2) the high must be greater than or equal to mid BB ( 18 , 2)
3) the low must always be greater than Lower BB ( 18 , 2 )

For Bearish Pin Bar ( shooting star )

1) the high must be greater than or equal to mid BB ( 18 , 2 )
2) the low must be less than or equal to mid BB ( 18 , 2)
3) the high must always be lower than Higher BB ( 18 , 2 )

note* BB settings
