Just a couple of comments related to the past dozen posts or so.
Regarding the time-in-trade: 10-15 minutes.
I have to say this is a bit long for a scalp trade...for ES or NQ for instance. Many of mine have been less than 3 minutes.
HOWEVER, it all depends on the market price action and activity level. I measure the latter by Ticks Per Second which I find invaluable. If that measure is low, your scalp trade is probably going to take longer to work out.
As far as analyzing multiple time-frames ? Well, looking at weekly charts seems a bit strange when your time-in-trade is less than an hour. HOWEVER, that might be helpful to develop a context for the market....trending up, down, or sideways.
For scalping, I think one must get into analyzing the microstructure of the market. This includes evaluating Inside BidSize, Inside AskSize, what trade volume is going off at the Inside Bid vs. Inside Ask, etc.
I've never been a big fan of Level 2 analysis (jigsawtrading) simply because of the extreme volatility of the orders beyond the inside bid/ask. In fact, it's been amazing to me to see how even the inside bid / ask order size changes so rapidly. Truly the algos are pulling/cancelling even these orders at a ferocious pace...thus, producing many "headfakes". I know the CFTC is monitoring the spoofing especially in the CME markets, but that doesn't really apply to the inside orders.
Hope this clarifies some issues here.
