I can't recommend stop and reverse strategies enough, nothing beats trading ranges from overbought to oversold, you take long profits because you have a reason to go short, and then you take short profits because.... you get the picture. Breaches of support and resistance are unreliable because they're schizophrenic in nature, first you think it's a strong foundation for a push up, but oh no, it's lost its bottle, down she plops, do you bail, ok she's away now, but for how long? what a drag, is this a halfway house, sort of support if the troops are there, oh crap a Dunkirk moment, back behind the Channel, have another think about it...etc. Overbought and oversold to my mind are clearer areas, you might be switching quickly between the two, but the direction you take is always clear, you simply limit the damage on flip flop moves. The resistance/support approach, and yes I know how popular it is, is too much of a line in the sand for me, too readily redrawn. The always in approach makes profit taking a no brainer.
