Long-Legged Doji

A long-legged doji is a particular candlestick pattern often read as a sign of indecision. It forms when a session opens and closes at almost the same price, leaving little or no body, but swings widely in between, producing long wicks, or shadows, stretching both above and below. Those long legs are the key: they show the price travelled a long way up and a long way down during the period, yet buyers and sellers ended in a stalemate, closing right back where they started.

Traders may take it as a sign that a prevailing trend may be losing momentum and that the market is at a moment of balance, often a warning to watch for a reversal, especially after a sustained move. However, the pattern alone does not confirm a reversal.

Example: After a long uptrend, a trader spots a long-legged doji forming at a high, with price having spiked up, fallen back, and closed near its open; she reads the tug-of-war as momentum stalling and tightens her stop, wary that the rally could be about to turn.

Long-legged doji

A rare candlestick pattern showing a balance between buying and selling pressure in the same trading period, appearing as a candlestick with a small body and equally long shadows.

Longs

Longs are the traders holding long positions in a market, or, collectively, the total of those bullish positions. When a desk talks about the longs getting squeezed, or the market being full of longs, it is describing positioning: how many participants are betting on a rise and how exposed they are if the move goes the other way.

The concept matters most at extremes. When almost everyone is already long, there may be fewer additional buyers to push the price higher, while a large number of holders may sell if prices fall. This can increase the risk of a sharp reversal as crowded longs rush for the exit. Traders watch positioning data for exactly this reason.

Example: After a long rally, futures data shows speculative longs in crude oil at a record high, and a contrarian trader takes it as a warning sign, reasoning that with so many already positioned for higher prices, even a small piece of bad news could trigger a cascade of selling.

Lot

A lot is the standard unit in which trade size is measured. In foreign exchange, one standard lot is 100,000 units of the base currency, with smaller denominations for smaller accounts: a mini lot is 10,000 units, a micro lot is 1,000, and some brokers go smaller still. Trading in lots standardises size so that everyone is speaking the same language about how big a position is, and it directly determines how much each pip of movement is worth.

The bigger the lot, the more money rides on every tick, which is why position sizing in lots is a central part of risk management. An oversized position relative to the account can magnify losses.

Example: A trader with a small account opens a single micro lot of EUR/USD rather than a full standard lot, so that a 50-pip move against her costs a few dollars rather than several hundred, helping to manage the potential loss in line with her risk limit, depending on trading costs and other applicable charges.

Lot

A measurement used to count the size of a single trade. Typically, investors start trading with 1 lot.

Lot-based commission

A fee charged by brokers for facilitating a trade that is based on the lot size.
