Inside Outside vertical bars strategy

Hi, my first post here. I'm not an experienced trader but I understand some of the basics. Anyway, I recently saw this Todd Mitchell video, which seemed really clear to me. I'd be really interested to hear your thoughts.

This is the strategy:

Trades based on a pair of Inside/Outside vertical bars using pivot points as directional indicators.
When there are two vertical bars, whether inside or outside engulfing, when the market takes out the high/low of the second outside vertical bar, it signals a strong trade either bullish/bearish.
can be applied to any market, any time!!

Of course it all sounds perfect on the day in question and I don't agree with his trade at 3.30ff but I guess that's what Stop Losses are for and 3/4 successful trades of is pretty good isn't it??
