FWIW, it was much easier trading on Sept. 17, 2001 than it is today.
On 9-17-01 the Nasdaq gapped below the April 2001 lows, providing a pivot area for price. Price tested that 1620 level on the Nasdaq and backed off. Price proceeded towards the eventual 1387 low over the next 4-sessions.
The closest proxy we have is the NDX 1806 August lows. Using the 2001 example, NDX 1806 ought to be a pivot area. Long above, short below is the easy play as we are near that line.
