$FuboTV (FUBO.US)$ Buy low and sell high for a profit of 10-20%.

$UP Fintech (TIGR.US)$ The luck has been pretty good these two days. Yesterday, I sold PUT22.50 for $6.20 premium, and today I bought PUT20 for $2.50.
Minimum profit: $1.20
Maximum profit: $3.70
The profit for this month is 5.3% - 16.4%.

$UP Fintech (TIGR.US)$ When the stock price is around $25, I sold the $30 PUT for $7.50 premium. If the stock price rises above $30 at expiration, the profit will be the $7.50 premium. But if the stock price falls below ($30-$7.50) $22.50, there will be a loss. So I bought the $25 PUT for $1.60. Now my position is zero risk and won't incur a loss.
The maximum profit is 7.50-1.60=5.90
The minimum profit is 5.90-5.00=0.90
During this week, no matter how absurd the stock price falls, the profit will still be $0.90. Of course, I still hope the stock price will rise.
