Add Qualifier to MT4 Indicator

I have an indicator written for MetaTrader 4 to which I want to add a qualifier.? The existing indicator is a simple indicator that draws up and down trendlines.? The qualifier would help me identify valid trendline breaks.? This is the qualifier: *? The price bar prior to an upside breakout must be a down Close. The rule is the opposite for downside breakouts. A qualified breakout is when the qualifier is met.? I want to add an alert that signals all breakouts and tells me if it is qualified or not.
