As the silver market finally bounced back, Muthu boy gazed at his gleaming coins with a grin. He leaned against the counter of his prata shop, seriously considering flipping the sign to ‘CLOSED’ for the afternoon to celebrate the windfall.

我只在84美元时收支平衡，因为我为期权支付了4美元。
在到期前，期权仍然具有时间价值和杠杆作用。在此期间，有效杠杆大致为5 ×。
因此，如果白银上涨20%，期权价值可以上涨100%左右，使我能够在到期前以接近8美元的价格卖出。
Take SLV 27 Feb call as an example:
Theta is 13.5 cents per day, weekends included
Last traded price: $3.10
Over the weekend (3 days):
$3.10 − (3 × 0.135) ≈ $2.69 theoretical value on Monday.
Now the dangerous part 👀
With ~7.4× leverage, if silver drops just 3%,
the option can fall to around $2.47 — that’s ~20% loss straight away.
To just break even, silver needs to move up ~2%.
That’s already asking a lot, just to get back to zero.
That’s why short-dated calls are brutal.
Better to buy longer-dated calls:
Less theta decay
More time to ride volatility
Easier mentally — you’re not fighting the clock every day
Time is your real edge in options.
Without time on your side, it’s easy to panic and end up making the wrong calls. @Ah_Meng
