Quote from RiceRocket:
Tape reading is watching different equities' price behavior in relation to eachother, and finding imbalances. An example would be to watch how the leaders in the S&P are trading, while comparing small cap leaders and how they're trading. You can see when real bids are coming into the whole market, versus just balancing and churning price action.
I like to watch many sectors at once, examples would be: xlf, xly, xhb, xrt, oih, uso, es, ym, nq.... etc. Then load up leaders in those sectors. You will start to see what really moves the market. Watching the time and sales, is a waste of time. Plus, it would hurt my eyes. I do watch market depth on the futures though.
Then I mainly trade the futures off what I am seeing in the overall price action of the market.
Some days, one sector will lead the whole market. That's another key, finding it early enough, you can be ahead of a lot of major moves.
Excellent synopsis.
In fact, during today's session you could tell that the broad market was acting with a "bid" in it and didn't need the oils to participate in order to rally.
I always track the OIH and XOI to see how it relates to the SPX. More often than not, the SPX is unable to rally unless there is participation by the energy sector.
If you overlay the OIH or XOI today on the SPX, you will notice that they were trading near their respective lows of the day, even though the SPX got an initial rally going up to 920, before pulling back to 892. The oils did not participate during that SPX rally, yet the SPX WAS IN FACT STRONG ENOUGH TO RALLY WITHOUT THE OILS!
This was a HUGE tip-off to me that the markets "tone" had changed from bearish to BULLISH.
Of course, the oils finally participated in the last 30 minutes ( CVX and XOM ) because these are some of the easiest names for portfolio managers to put money to work, in size, because of the liquidity that they offer.
But the "tip-off" and change in market "tone" was traceable back to the divergence that occured between the energy sector and the SPX earlier in the day.
