Bullish
Expecting or describing rising prices; a bullish market, candle or signal points upward.
Bullish describes an upward view: a trader is bullish on EUR/USD if they expect it to rise, and a bullish candle is one that closed above its open. The word comes from the image of a bull striking upward with its horns, the opposite of bearish.
It helps to separate three uses that often get mixed. A bullish opinion is a forecast. A bullish structure is an observation — for example, a series of higher highs and higher lows. A bullish signal is a rule firing, such as a moving-average crossover. A signal can be bullish while the larger structure is bearish, and that is exactly when many signals fail.
In currency pairs the word is always relative. Being bullish on EUR/USD is the same as being bearish on the dollar against the euro.
On a short expiry, a bullish view becomes a higher trade: the green Buy button in the Sky Trade terminal (or the W / ↑ key). It pays only if the price is above the entry at expiry; being right “eventually” doesn't count. See trend lines and channels for reading direction on a chart.
On the M5 chart GBP/USD makes three successive highs at 1.2640, 1.2652 and 1.2661. The structure is bullish, but a Higher trade still needs the price above its entry at the moment of expiry.
