General Advice, worth all that you paid for it, gleaned from my various experiences over years:
Do not try to anticipate price decline, this leads to dismay and losses. Wait for the break then short when it's dropping, you can trade daily or weekly puts in a selloff very profitably, buy atm strikes on the way down and add the next strike as it moves down. Selloffs move fast and can easily bring $5-10 contract appreciation in a few hours. Dailies selling for $1 turned into $10 last Tuesday!
Useless to buy expensive puts for $8, $10 or more trying to pick the top. Just enter when it's already moving, a sure thing and no-brainer.
See how painful it was to guess that 4200 was a double top, then it moved to 4230+ at new ATH?! Nuts! Might see higher still IMO.
Took me a long time to figure out this simple strategy;
"Do what the market is doing; buy calls when the prices rise, and puts when they decline.
Don't try to guess when it will pivot, just ride the wave and take what it gives you."
Watch the Elliot waves in daily price, when you got 3 legs down, selling is usually just about done. Be really, really careful about buying calls in a downtrend! Sometimes you get a deep fourth leg down... look for a higher low to enter long after pivot confirms.
It's price surfing, no guessing involved!
