When a succesful trader talks about 8 SL in a row it puts a trader into the right perspective. Madan has also talked in a good detail about series of losses.
One of my trader friend he was executing 3 different strategies and all his strategies failed last month giving rise to a big hole in his account and then we had a long discussion on running multiple strategies. The guys is a successful trader since last 4 years continuously profitable year after year. Losses and series of loosing trades is something a mechanical trader has to take in his stride and go on with his job.
I cant say much about discretionary trading and leave it to others
