The only thing that can change is the key features of exchange and the introduction of new features such as the now known stop lose features on some exchanges it was not there in the time past.
But nothing much has changed in trading it still has the old traditional way of doing it.
Stop loss was a big help, a lot of people would have lost a lot of money if it weren't for the wonders of stop loss, I mean not everyone is always watching the market 24/7 so it's a good thing that we have that kind of feature so we can rest easy that we won't lose everything when we look the other way. I definitely agree that there's not much that has changed all this time when it comes to trading, it just looked different because people have different if not unique approach when it comes to trading that it's sometimes distinct to only one person.
There are many people that do not like to use a stop loss but I think that is a huge mistake, after all we know that the volatility of the market is extreme and it is not rare for the market to suffer a drop of 10% in just a few hours, so those that are not using a stop loss are taking a huge risk, and there are even some traders which use leverage without a stop loss and this means that even a very small movement of the market is more than enough to wipe them out, and despite our warnings they keep doing this so sooner or later they will lose all their money due to the high risks they are taking.
