A pip, short for ‘point in percentage’, is a very small measure of change in the value of a currency pair on the foreign exchange (forex) online market. It can be measured in terms of the quote or the underlying currency. It is a standardised unit for the smallest amount by which a currency quote can change, which is usually $0.0001 for USD-related currency pairs. A fractional pip or point is equivalent to 1/10 of a pip and there are 10 points to every 1 pip.
When trading forex, spreads with low pips (0.0 pip spreads) indicate that a product is traded very frequently but pips can also be used for risk management tools like Stop Loss orders.
Knowing your currency pair’s pip value allows you to manage your risk exposure, and potentially make the same profit across pairs. For example, if your Stop Loss equals 50 pips, the Take Profit could be 100-150 pips - as many think that having a SL/TP ratio of 1:2 or 1:3 is a good benchmark.
