The price is based on the tendency of the market participant
the price changes are based on the supply and demand power
when the tendency of the groups changes, the supply and demand will Chang too
the gaining and dumping of the price are based on the group tendency
in fact, the price is the decision of the participant in the market to buy and sell the one concept
so
the movement of the price is based on the direct decision of the every participant of the market too
some traders are use technical analysis for their decision some of them using the fundamental and some use the stars or their luck, but the most important point is that this is the people who make the decision even in bot trading this is the human decision for making this program and gaining profit or loss
in simple word, every single trader open position based on their beliefs and their point of view about the market trend
When the every single participant have a tendency and believe in rasing and gaining trend and market and open their positions, it makes others to believe on this scenario and open the long position and when the proper amount of these participants take part in the long position the whole market tendency become bullish and bullish candlesticks appear.
