Yeah it looks like it's worth a try there... I myself would just keep a stop under the central pivot and size the trade accordingly, not to take on something that is a large part of my funds to trade with but that's with any trade really.
Looks like you found a chart that works well with the Vortex Indicator repeatedly. I guess you only need one and can trade it over and over!
I would say however right now the weekly vortex trend is bearish, so if trading bullish counter-trend expect those moves to be smaller than the bearish ones as they have been recently. So this would be a chart one would want to keep an eye on and have fast reflexes.
