what you described is a simple bullflag to me
do you only trade long?
why do you need bb ? - they're lagging like all price indicators
and what about the 5 min charts - flags work pretty fine in any t.frame
a) Call it what you like. I just call it buying new highs at the right time of day.
b) Short is just as good.
c) I use BB because I find them the best filter for which breakouts to trade. I couldn't care less what they are supposed to be (lagging, leading or whatever). Mine is not to question how or why something seems to work. I just trade what I see.
d) I'm not trading "flags". I'm looking for breakouts that fit the rules on Page 24. Nothing more nothing less. I'm then using my skill and experience to fine tune when to move the stop, which trades to filter out (via 4 market analysis). If you can make money in another timeframe with this stuff, then be my guest. Just don't step into one minute chart territory because there some serious "expert traders" at that level. Right, Jack?!
The way to make money is to tell yourself you are a moron. I do this everyday. In fact, I make my wife tell me - it has added impact that way

Then to patiently wait for the very best signals and not to trade when in doubt. The skill comes with the grey areas: signals that technically meet my criteria but feel wrong. Ths skill comes with good stop movement once in a trade. If this method were 100% mechanical than it wouldn't work.
Start getting your head around the idea of buying as high as you can, and selling as low as you can. And only doing this once or max twice a day. The exact opposite of how most people think and try to trade. What I've given you is a starter for 10. You figure out the grey stuff. I ain't here to give your hand and stroke your forehead with soothing words. There's plenty of Guru's around for that job. Right Jack?!
