Topic: bar high & bar close

I would like to build a strategy as follows:-
1) setup bar has lower high than previous bar.
2) Setup bar closes down.
3) Enter long at 1 pip above bar previous to setup bar.
4) Exit at TP or SL.

I set opening point of the position to 'Enter long at previous high + 1 pip'
Opening Logic 1: 'Enter no more than once per bar'
Opening Logic 2: 'The bar opens below the previous opening'

How do I tell it 1) & 2) above?

Grateful for some help please.
