SPDR S&P 500 (SPY)

[USDollar]

5 min and daily are not a good combo, too far apart

the frames have to be more close to each other

also , crossovers are laggard and buggy

(i.e. buying) to make it work better I suggest using 10 and if R of that is violated then buy on kiss back of broken resistance
of course opposite for selling

Today would've worked flawlessly as well whereas the crossover as you correctly mentioned did not work (*the buying was on Fri tho, today only the selling ... so far)

Speaking of which, I see some attempted buying, but 282.48 intraday resistance is not being cleared yet, so too early (?)

oh ooo , they are working on it as I write ?!
