I have a question regarding MooMoo trading for US stock.
I have purchased a stock at the price of $55. Currently it's at $59.

I would like to set a stop limit order to sell it when price down/reach $58 and cancel the trade if it drop below $55.

In the stop limit option, I'm seeing "Trigger Price" and "Price".
I'm confused on this. Based on my plan to sell at $58 and cancel if it hit $55.

Trigger Price : $58
Price : $55

Am I correct or need some expert to help on this. Thanks.
