horse618 : then short it yourself , if you have a winning lottery ticket why tell the whole world ?

horse618 OP 105251507 : of course i'm aware. im sharing my advice to those who buy in "late" , when price rises or drops rapidly resulting in losses , to not trade on fomo. everyone has their own standpoints. anyways whether it goes up or down , there is opportunity to make .

horse618 : if you don't plan on actually holding onto the shares , it's better to just sell for profit premium

horse618 Hu8t C8t OP : in a case where you exercise , you will be obliged to buy 100 shares of the stock at your strike price if your option is ITM ( in the money ) so you need to have spare cash but you will also lose all extrinsic value , means the new premium u see is gone therefore , i suggest not to exercise unless you want to hold onto the stock and hope the share price keeps increasing so u can profit from there by selling however many of ur 100 shares.

horse618 Hu8t C8t OP : yes correct , if your option is deeper ITM you can exercise to buy the stock at your discounted rate (strike price) x 100 shares , and sell it off at the market value for profit. however do note that you will lose all of the current premium and there will be transaction fees for sales/orders. your profit would solely be from the sale difference of the current market price and ur strike price x 100 shares. therefore unless your call option is deeper in the money , you're better off just selling the option for profit premium.  
my own suggestion is to only exercise if your option is deeper ITM , so u can exercise and sell for profit instead of exercise already then need to hold and hope for the price to increase more then sell. as prices can fluctuate , you won't want to end up holding 100 shares of a stock you can't sell for as much profit right ? just managing risks

horse618 sendhelp : time decay is dependent on the theta , the delta is how much your option premium changes for every $1 , and the gamma in basic term is how much is added to ur delta for every $1 increase , the vega is the rate of change based on the implied volatility (IV) , rho is just the interest rate which i think is the least important.
in the moomoo app below on option page there is a profit probability , this only applies to the chances of your option hitting the underlying stock price breakeven and being able to exercise at a profit but honestly if u don't have the spare cash to buy 100 shares of your strike price or want to hold onto the shares , selling the option for the profit premium is more ideal because if you exercise you lose all extrinsic value and the new premium.
personally i don't really look at the profit probability so much. i look at the greeks more , and choose a good strike price and expiry date. can still profit from selling even if your option is out of the money (OTM) . but do not hold onto your option until expiry if it's OTM , it will expiry worthless and you lose 100% cost for that contract.
hope this helps.
