What are supports and resistances? Support and resistance are often called “key levels”. They are price levels at which the stock price has inverted its trend. If the price rises and then inverts its trend moving down, the highest point it has reached is called resistance. If the price has gone down and then starts rising, the lowest price value is called support.
These price levels identify supply and demand zones, at which traders have increased their operation volume and have shown some interest. That’s why, as soon as the price gets closer to a key level, traders must keep their eyes open and see what happens.
