If I had to break it down I think my motivation would be about 1/3 each of
1) add variety to the day
2) potential profit
3) meeting new people
None of that is worth even a small amount of anxiety or frustration - I have enough of that. This would need to be an anxiety reducing proposition.
garachen, from some interactions we've had in the past and reading some of your threads i know you to be the real deal and that is quite rare on this forum. You seem to have done quite well for yourself in this business and given your motivation i have to say i am quite skeptical that you will get the benefit you are expecting out of this exercise. I call it that because in my mind i cant justify undertaking this as anything other than a mental exercise.
4-5 years ago i turned one of my good friends into a full time trader. What i did was fund an account 100% then go on to teach him my methods in detail. We were in video chat daily as i traded the account in front of his eyes explaining all my actions. After about 3-4 months i ran up the account 100% at which point i took my initial investment out and turned the account over to him at a 50/50 split. Our roles were reversed. He was doing the execution and explaining the reasons behind it as i only intervened if i disagreed. It probably took another 6-9 months until i was comfortable that he could make it on his own. Fast forward to today, he still trades the account which is now in the 7 digits as well as his own personal account. Even though in the end i profited quite nicely from it my motivation wasnt monetary at all. I never intended to keep the account open this long but given the drop in vol the past few years the frequency of trading dropped so it didnt require much effort to keep it going.
Having said all that if i ever were to do this again the reasons cant be monetary at all as the economics behind it simply do not justify it in my opinion. It cant be anyone random off the street and i certainly wouldnt structure it as a business transaction. If your edge is real i can't imagine a single instance where the economics behind it work over the long term unless you are training someone to be a desk jockey in the higher frequencies. Perhaps you can invest this time and extra effort in some other aspects of your life outside of trading which in the end would add variety to your day as well as allow you to meet new people and improve the quality of your life. Unless you are the real life version of Josh Brolin's character in Money Never Sleeps where you always want "More" as just a score then i can't imagine this to work out well, much less as an anxiety reducing proposition.
