The BUY button

What exactly you are claiming when you press it.

State a buy idea as a checkable claim rather than a wish.


What the BUY button fixesBinoDex
What the BUY button fixes. The entry price

The BUY button means exactly one claim: at expiry the price will be higher than the entry price. Not “much higher”, not “after a rise” — just higher, by at least the minimum step.

So an idea always has two halves: why I expect a rise, and what will prove I was wrong.

The reason
— An upward structure, price bounced from a tested support zone
The invalidation
— A close below the previous low
The expiry
— 5 minutes — about as long as a move to the next level usually takes

If the second half will not form, it is not an idea. Without a boundary for being wrong you can neither assess the risk nor draw a conclusion afterwards.

A psychological trap: beginners press BUY more often, because a rise is subconsciously received as “good”. The market has no favourite direction, and your statistics should not either.

The usual mistake

Buying at the end of a sharp impulse, when the move already looks obvious. That is the worst reference point available.

Key takeaways

  • BUY is the claim that price will be above the entry at expiry.
  • An idea holds a reason and a boundary of invalidation.
  • A lean towards buys is a psychological pattern, not a market one.

A note from Leon Mercer Academy

Write the entry price down yourself before pressing. The platform will show it too, but a written number is harder to move in your memory in your own favour afterwards.

A practical example

A bad idea: “three green candles in a row, I am buying.”

A working idea: “upward structure on M5, the correction ended with a higher low, buy for 5 minutes, invalidated by a close below that low.”

The second forms in one sentence and contains the boundary at which you admit the mistake.
