Quote from gjann:
I understand the Value area in the Market profile and the POC. But I would appreciate it if you would explain the rotation factor, the mean price and the volume per period and the "singe tpos".
I have also found from my own trading that the Globex High and Globex Low are key numbers that often hold as support or resistance during the day session.
Most traders have only a rudimentary understanding of the market profile and its application to day trading. They are using yesterday's VA and POC.
The greatest value in daytrading with mp is in the evolving market profile for the current day. If you don't learn this, you have lost the real value of using MP to daytrade.
The rotation factor is a standard MP term whereby the 30 minute bar is compared with the previous 30 minute bar to determine a value: +1 for a higher low and +1 for a higher high, -1 for a lower low and -1 for a lower high. Thus the rotation factor for a period can vary from +2 to -2.
Personally, in addition to plotting rotation factor intraday, I also plot 1) the midpoint of the period as compared to the volatility, 2) the average price per period compared to volume per period both of shares on NYSE and contracts on es, and the midpoint per period along with the mean price (based on total tpos) and the midpoint of the day session.
TPO refers to "time price opportunities", or alternately the slang is "that price occurred." Single tpos are significant, and should tend to lend support\resistance intraday, and should be traded similar to how gaps are traded.
What else to you need? Go get the money!
