There are popular pairs, with whom all the acquaintances with whom I have to trade for an exotic steam, need to be prepared separately
Exotics tend to be good for swing trading.....however - this means smaller positions. I think of them more like investments....USD/TRY would have been a great example over the last couple of years.
The most common reason for traders avoiding the exotic pairs is the less trading volume and low volatility, due to which there are more chances of slippage.
