Or you can:

Buy 100 AMC shares = -$6800

Sell 1 AMC $75 call = +$3000

Net cost for AMC = $38

(Take a look at all those calls, most strikes expiring > 2weeks from $60-80 are around $30, which is like 40-50% of security price! Price difference of each strike is smaller than the strike intervals!)

At expiry, if:

AMC < strike (calls expire worthless) = max gain $7500-6800+$3000 = $3700

AMC >strike (I get exercised) = Max gain capped $3700

AMC stay at $68 = gain $3000

AMC tanks = $6800-$3000= $3800 max loss (I lose net cost of shares)

Unfortunately, tiger brokers does not support covered calls. After chatting with Customer Support, I was told “system does not support covered calls”.

I was told that in the event of further price increase, I would be asked to deposit more and more funds, or else the will liquidate my holdings, including the AMC shares. If they liquidate those, my covered call will become a naked call.

My losses should have been capped to what I paid for the shares, less option premium received (about $38/share). Instead, it could become *unlimited*. This results in sabotaging the entire trade and destroying my relatively secured position.
