Hello friend @alokkumar121
True, I also have 4 years in this environment and the LOS problems seem not to stop. Considering that we are talking about big companies, well known and reliable, I still don't understand how these things can happen.
Luckily this is a big exchange and has a way to respond to customers, but it could happen, if they are bigger thefts, that the company does not respond and customers lose their money.
