The Importance Of Scratching Trades

Scratching a trade means breaking even (plus or minus a tick) because the
trade is no longer moving in your favor. The ability to scratch trades is one
of the major differences between successful traders and everyone else. Most
people can’t stomach the thought of not making money on a trade and therefore
allow break-even trades to turn into losers.

Not every trade works out; how you handle these trades will determine your
long-term success as a trader.
