Contingent Sell Stops

Hi Pat – Three questions:

1. You mentioned a contingent sell stop price of 1.25% below the buy stop. Is that a typical percent to risk. What’s the minimum or max you would risk on a contingent sell stop?
2. I made a mistake buying too much ZIM before the close today. Do you ever trade in the after-hours market?
3. When is it time to “put on the gas” in terms of position-sizing? A couple of positions are working. However, I’m concerned my initial position size was too small. I have FOMO and want to buy more, but it’s seem stupid to add too much more now. Thanks.
