Write the invalidation before you like the entry
The line that kills a trade is a place on the chart, chosen while you are still calm. The stop is only the order that follows it.
Most plans that fail in our room fail in the same place. The entry is described with care, and the reason the idea is dead is a feeling that arrives later, usually after the loss is already larger than the trader meant. Trade planning starts earlier than the order. It starts with the price that proves the idea wrong.
We call that price the invalidation. It is a location on the chart, not a mood and not a won amount. The stop is the order you will actually send. The two belong on separate lines of the plan. Mixing them is how a stop becomes a number you can nudge.
A location a stranger could find
On a Thursday in June a visitor brought a daily chart of a liquid KOSPI name and a long idea based on a higher low. Asked where the idea died, he said “if it starts to look weak.” That sentence cannot be found on a chart. The room asked for a print. The higher low was visible. A daily close back through that low would mean the swing he was buying had failed.
He wrote: “Long idea is finished on a daily close back through the higher low at the price marked on the 12 June print.” The stop order sat a small distance beyond that close, so he was not waiting for the close and then discovering he had no order. The invalidation was the reason. The stop was the instrument. Both were written before anyone discussed how attractive the entry candle looked.
Pain is not a level
A loss limit in won still belongs in the plan. It is the size question, handled at the desk and on evening three of the studio. It does not replace the level. If you only know that you will exit after you have lost a certain sum, you will sometimes exit in the middle of a range, and sometimes hold a broken swing because the sum is not used up yet.
A practical test we use in the chart room: cover the entry with your hand. Can another person point to the price that ends the idea? If they cannot, the plan is not finished, however neat the rest of the page looks.
Write it while the idea is still only an idea
Invalidation written after the fill is an excuse dressed as a rule. The studio asks for the line on the board before the entry condition is polished. People dislike this order. It makes a pretty candle wait its turn. That is the point. A candle is easy to like. A level that kills your idea is not, which is why it has to be written first.
If you sit with us, bring a chart where you already want to be involved. We will ask for the invalidation before we let you describe the entry. Leave with one sentence a stranger could trade from, or with a blank line and a reason to stand aside.
