I agree with these 2 statements nothing else. He’s offering you his opinion Being honest he tells you he is purely a long term trader and that part of the post is fact.
Like all the posts to your question; these are traders opinions based on like above that I quoted opinions. Some based on their personal experiences and some just what they heard.
So. . .here’s my opinion based on my experiences.
As far as Short Term, Long Term trading and Everything in between; the majority of ideas on how to trade will all work sometime; but nothing works all the time.
Before you do anything distinguish between a fact and an opinion. 2+2=4 (fact) this the greatest, never before reveled, holy grail of anything is; opinion. Next base your decision to; or not to, by applying relevant facts, relevant options, pick on the balance of probabilities the least of the evils.
One of the top pieces of advice I got was; Realize that you will make the same mistake more than once. The trick is to try and make it the least amount of times as possible.
When it comes to trading in my opinion there is no one size fits all. It’s about taking a lot of information, filter to separate good from the bad and design a learning strategy, operating strategy that works for you and your particular experiences and circumstances.
That’s what I would tell me.
