The green resistance zone continues to hold. This is a place to take long profits if you've got 'em and to short if you're so inclined. (You can always buy again if it breaks out to the upside.) Trading Range... buy support, sell resistance until the market breaks out. The rising diagonal line doesn't mean anything yet. It's only "2 points to define a straight line". If market tests this line and holds.... it means something at least in the short term. A "back test" of 20560 which bounces is a technical buy if it holds.... as would a be a test of 20440. Now you know what I know about this chart and the market at this point in time. Price TA... KISS baby. GL with navigating this volatility and uncertainty of times... FWIW...
Most important action in the markets occurs around support and resistance. (If S/R holds, it means something. If S/R breaks, it also means something.) Couldn't be more simple. (Not the same as "easy", as I've said many times before...psycho forces, you know.)
Just like KCalhoun said he was done with hookers, You and Ken should do seminars together. Mix in some PA with some TnA.
Support Resistance concept In real life ..... Buy Support. Then price pierces through the support Sell Resistance Then price pierces through the resistance Chase Breakouts Then price reverse direction Trade with very tight stops. Then you get whipsawed/stopped out. Then the price continues in your favor. Finally, after many many years, @scat is drawing a band, not a line. Soon the band will be a mile wide.
