Breakout Trader

What Does Breakout Trader Mean?
A type of trader who uses technical analysis to find potential trading opportunities, identifying situations where the price of an asset is likely to experience a substantial movement over a short period of time. Breakout traders generally look for key levels of support and resistance and will place transactions when the asset's price passes through these levels. Long positions are taken when the price of an asset breaks through a level of resistance, and short positions are taken when the price breaks below a level of support.

Investopedia explains Breakout Trader
Many breakout traders find trading opportunities by identifying chart patterns such as channels, ascending triangles, descending triangles, head and shoulders, etc. These types of traders will generally set up target prices to be equal to the distance between support and resistance levels.
