What Is Scaling Out

Scaling out is closing a position in pieces at different prices instead of all at once, so that each piece banks its own result and the piece left open keeps the original stop. This paper shows you 0.30 lot of the euro against the dollar bought at 1.17166 on 17 December 2025 and closed in thirds at 1.17316 and 1.17466 with the last third still running; the idea as a train that leaves a carriage at each station; the lines on the fifteen-minute chart; the position drawn as a ribbon whose width is the lots open; and the History and Trade tabs on your platform, where the closed pieces and the open one sit.

One position, closed in pieces

Scaling out is closing a position in pieces at different prices instead of all at once. Take the euro against the dollar, 0.30 lot bought at 1.17166, its 10:15 close on 17 December 2025, with the stop 25 pips below at 1.16916. As the price rose, 0.10 lot was closed at 1.17316, first traded at 15:15, 15 pips up and 15 dollars at that size; another 0.10 at 1.17466, first traded at 17:00, 30 pips and 30 dollars. The last 0.10 was still open at the end of the day with its stop where it began, 25 dollars at risk. Forty-five banked, one piece running. The exit prices are examples; the arithmetic is not.

A train that leaves a carriage at each station

Picture a train that leaves a carriage at each station. It sets out with three, uncouples one at the first station and one at the second, and the engine runs on with what is left. A position closed by scaling out is that train. Each piece closed is a carriage uncoupled at a price and left there for good, and the piece still open is the engine, shorter than it was, still on the line. The stations are prices, 1.17316 and 1.17466 here. The engine does not know where the line ends, and the carriages left behind do not move again whatever it goes on to do.
