Long position is a speculative way in futures trading. Speculators estimate securities, commodities, etc. If the price tends to rise, buy in advance, and then try to sell after the price rises, in order to obtain the difference benefit. This kind of speculation is based on buying first and then selling, and speculators have more securities or commodities to sell, so they are called "bulls". As opposed to a bear.

The bullish pattern means that there are more buyers than sellers in the stock market, and the stock market is bullish.
