It is important for us to know our profit before we buy the option put.
For example, for 100 stock XYZ, the strike price is $48, premium is $0.05
if the stock price goes down to $45, how much can you earn?
The formula is quite easy.
Profit = number of shares * (strike price - premium price - current stock
price)
Therefore, the answer to the question above is
100 * (48-0.05-45) = $295
Hope you enjoy it.

但要知道好多人都不excute的。没到期就是premium倒来倒去。算不出profit。

请问能详细讲讲吗？
什么叫premium倒来倒去？premium不就是固定的吗？买option的时候就固定了，对吗？
另外，option不执行，不就是等过期吗？过期了，不就交premium吗？
你要赚钱，就必须execute。

单边long call/put风险非常大，长期做绝大部分都会亏钱。Short call/put风险会小
些，但是也不是说short了就能不管的，如果价格超自己不利的方向大幅走动是需要cut
loss或者hedge的。

奥普欣收费真是太tmd的坑爹了。
我搞不懂为什么还有按照几手合同来收费，而买卖股票100股和1000股都一样的手续费

这个公式算的是到期时候的profit，到期前有股价，volatility和time decay等影响因
素，要用P/L图去看
