A bet if you want it to be... i prefer to trade...
I think of opening a business, a trade, or most business decisions as a bet, but sure ....call it a trade/bet/wager/investment/business decision. It was not meant to offend.
(chart based trading, expected ranges based on vol as i am not holding to expiration]
...............
Yes at expiration they are 0 or 1.00 but don't hold till then not wise...
are these cash settled.....why not simply hold to expiry, as opposed to exit especially if settlement is easy, and you are trading very close to it - are the costs that much different? or are there other hidden issues?
So understanding delta, gamma, theta impact on delta, vol impact on delta etc.. helps one better grasp the pricing model. Though honestly you don't have to grasp it to trade them effectively.

if market is at 1000
i buy at 980 strike with 2 hours till expiration
the market can stay flat - i profit
the marekt can move up i profit
the market can move down and settle 1/10th of a tick above 980 and i profit
the market could fly down and move back up an settle 1/10th of a tick above 980 i profit
the market could fly down and say down i lose to limit risk the market cold move down and i exit atm to minimize risk and lose
so i could be right about price, wrong about price, right about time, wrong about time, right about price and time, only if i am wrong enough about BOTH price and time do i lose on the trade
it does not have to be complex though - keep it simple that is what works... and exit before expiration!
I agree - keeping it simple is easiest....I guess that is one of the confusing issues of this whole thread - you dont need to worry about all the option maths (unless you are arbing it, or spreading it, or similar), and which is why i wanted to get to the crux of what it is you are trading.....the delta of a strike, rather than the arguments of replication, equivalent payoffs etc.
IMHO - All the rest is unnecessary and which is why i summed it up as a bet against the delta - on expiry (as you say) its all 0 or 100. - So ITM longs are good, OTM shorts are good. Period
thanks for the info,
it sounds like something I will look into (though my skeptical old mind says, costs, and spreads will be the issue here. - Although maybe everything these days is so automated, old school will work again!)
