You don’t have to look at the thread or follow it if it makes no sense to you; why waste your time? But then if you look at the thread because you feel like you have to, then kindly read it properly before posting your comment.
Everyone ought to be addressed politely irrespective of their age, gender, religion or whatever. It is no point posting comments or making insinuations that go below the belt.
Should anyone have comments like this kindly keep them to yourself. You are in no way obliged to participate if you do not have a reasonable and constructive input or if it makes no sense to you. If you’d like more clarity because there is something you do not understand feel free to ask.
No where has it been mentioned that those in the house/flat share will be using the same trading system (there are so many out there) neither has it been mentioned that they would be taking the same trades with the same TP and SL.
All the best!
