Thank you Makingmoneystill for sharing your experience in this wall. I thought Comsec wouldn't follow me for small trade and continued trading from Comsec. I could be one of the oldest online retail account holder. I opened the account in 1998. I never suspected comsec praying on their clients.
As your suggestion, I will open a account with other brokers and start trading from them. Yes, after bitter experience in this afternoon, I started to watch Youtube video about the bot and got so many postings. Now, I understood, how they pray on vulnerable novice traders. Now on I will change my trading strategy and broker. Once again, thank you for sharing your experience.
