1 · See it
Find repeated size
One huge print is a headline. The useful case is the same side of the same market getting filled again, at a price you can still name.
A reading desk for large Kalshi prints
Read the print before you follow it.
A whale fill is a trade that already happened. This desk prices what is left on the board. If the condition can happen again, write it as a rule and test it. If the leftover payoff is tiny, leave it.
2 · Price it
Use the number above
Contracts settle at $1 or $0. The cents still on the board are what you risk. The rest is all you can make. This is arithmetic, not a quote from today’s book.
3 · Write it
Make it a rule
If you would take that price the next time it appears, write the market, the side, and the ceiling. Test it in Paper before any live order.
