What it does
Most traders know they should set a stop order — but figuring out the exact numbers is annoyingly manual. This free tool takes your cost base, current price, and how much profit you want to protect, and instantly gives you: • Your stop-loss price • The trailing stop % to enter directly in your broker Copy buttons let you paste the numbers straight into your order form. No sign-up. Works on mobile. Free forever.
Free calculator for stock traders. Enter your cost base and current price to instantly get your stop-loss price and the exact trailing stop % to enter in your broker.
This % is how much of your profit you want to protect — not a % of the current price. The price at which a stop-loss order triggers. It locks in a portion of your profit based on the profit lock-in %. Brokers ask for a % below the current price when you submit the order — not a fixed price. This converts your stop price into that %. Enter your cost base (what you paid per share) and the current price , then choose how much of your profit to lock in. The calculator gives you two numbers to use in your broker: Both numbers update instantly as you adjust the profit lock-in slider.

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
