The level of support is this area or range on the chart, where the price meets demand from buyers and jumps higher. In order to qualify a certain level as “support” this level must have been tested at least 3 times before, without the price dropping much below it. Its never a fixed a price, but rather a zone. 

We say that as the prices drop, they get supported from fresh new demand. You will find support when the stock is dropping. As it drops, it becomes cheap, which means attractive for investors to buy. Normally, stock buyers are trying to buy shares at their support levels so they can sell later at a higher price.

There are certain indicators such as Pivot Points, which will show you where the levels of support are, but usually we look for them with a naked eye. You simply look at the candle chart and see which price area was tested a few times and every time after the stock touched this level, the price jumped. It is important to remember that 1. support levels can be both horizontal and diagonal and 2. if the support zone gets broken, the price is expected to dive even deeper down. A broken support will transform into a resistance level on the way back up.
