This is great, as the markets are open so long, we can enter or close a trade whenever we need to, whereas if you were trading stocks on the NYSE you can only trade during market hours, and once the market is closed you have to wait until the next trading day to trade your position. This forex help tip can really save you when there is a big unexpected political or news release and you need to close your position right away.
The problem is that this is where traders are most likely to succumb to overconfidence bias. It's not uncommon for traders to complete a winning streak and then believe that they can't get anything wrong in the future. To believe this is of course unwise, and is only going to end in failure. Make sure you always analyse your trading sessions and look at your wins and losses in detail.
