I consider roadblocks to be between the 80-100 on the 2 or 5 min chart.

So I'm a pretty simple trader. I actually just use the RSI strength indicator to tip me off if we've potentially hit a new low or high and then watch for it to start moving in the opposite direction and once we've also passed over the 20 SMA, I start looking for a good entry and I ride it till the RSI hits another roadblock.
