Using TD9 intraday with volume & RSI. SPY example

I find that when pairing nine with Volume and RSI11 it gives fairly reliable signals during the slower market hours. E.g. East Coast lunchtime.

Note here how the rising 9 ending at 12:30 has declining volume yet RSI continues to climb.

Similarly, the 13:00 falling 9 sees a volume spike and sudden decline as the RSI11 recovers from extremely oversold levels. This is also a great example showing that recovery doesn't always mean rebound back up, watch for consolidation without breaking the top of #8, it's likely leading to further price declines.

During peak volume times in the day I find that TD9 just gets run-over due to the market driving forces.

Final thoughts, have your daily charts with key support/resistance and Fibonacci levels tracking and recent heavy rise/fall and notice how TD9 plays out as price action reaches those key levels.
