Scalping

A trading strategy that attempts to make many profits on small
odds changes. Traders who implement this strategy will place
many trades in a single day or a single match in the belief
that small moves in player price are easier to catch than large
ones.traders who implement this strategy are known as scalpers.
The main goal is to back (or lay) a players at the back (or lay)
price and then quickly sell them a few ticks higher (or lower)
for a profit. Many small profits can easily compound into large
gains if a strict exit strategy is used to prevent large losses.
