GTC through a split calculator: what happens to your old stop price
A good-till-cancelled stop outlives the split, and the price on it may not. Enter the split and see where the stop should sit.
How it works: a split changes the share count and the price, not the value of the position. A 2-for-1 split gives you two shares for each one, at half the price. A good-till-cancelled stop at the old price has to follow. Divide the old price by the ratio to get the matching new price. Check your own order to see which of the three things your broker did. The tool shows the matching price, the shares after the split, and what each choice means.
Same value, new numbers
The adjusted stop covers the same dollars as before. If the old stop was $50 on 100 shares, a 2-for-1 split makes it $25 on 200 shares. Both are $5,000. The details of how brokers treat open orders are in stop orders after a stock split.
The two ways it goes wrong
A stop left at the old price after a forward split sits above the new price. A sell stop at or above the market fires at once. A cancelled stop leaves you with no stop at all and no message in the chart. Both are told in the stop was cancelled after a split. The ratio math alone is in the stock split calculator.
