Position size vs notional
Contracts and USD notional look large. The size that matters is how much capital that size puts at risk to the stop.
Tiny prices hide large size
Meme perps and high-decimal coins make a ‘small’ USD print look harmless. Notional and contract count tell a different story. Fibonomy converts the row into quote-currency risk so zeros after the decimal cannot hide leverage.
Size changes are part of the story
Adding to a loser changes capital at risk even if the ticker did not. ‘What changed’ on a position includes size, not only price.
One size is not one bet
Two correlated names with ‘reasonable’ size can be one concentrated bet. Rank by capital at risk, not by how familiar the ticker feels.
Apply this to an open position
Definitions are useful. The next step is seeing mark price and capital at risk on the positions you actually hold.
FAQ
Should I size from notional or from stop distance?
From the loss to the stop (or liquidation if no stop). Notional without a stop is incomplete on purpose.
Does Fibonomy size the trade for me?
No. It shows the size you already have and what that size does to account risk. It does not send orders.
