The Market Watch allows you to display the spread of a particular symbol.
To activate this right-click anywhere on the Market Watch and select Spread.
Please note MetaTrader4 quotes the spread in MetaTrader4 points – this means in order to find the pip value you must divide by 10.
For example 10 point spread is equivalent to a 1 pip spread.
*Spread is the common trading cost for online trading, but your broker might charge you trading commissions besides the spread.
