Quote from Ghost of Cutten:
You said "In my over 15 years in finance and 10 years in professional bank trading environment have I not seen a single successful day trader" and I challenged you on that, then you changed it to requiring a whole 10 consecutive years of daytrading profits.
I am saying that there are traders who are consistent and successful at daytrading. At no point did I say I had daytraded exclusively for 10 consecutive years, let alone needlessly spent money getting a full audit each year (audit requirements where I lived were for >1.5 mill annually, and I have no clients, so why would I spend time and money to do that?), or kept 10 year old account statements.
Oh, and it is easy to make 20% per annum - 10k to 100k in a decade is >20%, for example, and I did that in my first year. Daytrading is usually done with small amounts of capital, and is usually not very scalable, so % returns are not really a useful metric.
In short - it's possible to be a successful and consistent daytrader. If you wish to bet a worthwhile sum against that proposition, let us know and we can discuss reasonable - not ludicrously demanding and unrealistic - terms for that bet. If not, then you should accept that your claims are wrong and you aren't willing to back them up.
I will just state that I have 7 significantly profitable years daytrading, and one moderate down year early in the last decade. I class that as successful and consistent. My daily win rate has been high, rarely having any down months, and % return on capital is very good. And there are many daytraders out there much better at it than me. The main problem is it is hard to scale - I would make no more with $5 million in my account than with $100k - so after a certain point it becomes better to work on position trading and investing. After a certain account size is reached, 20% compound return on capital for 10 years will make more than 6 figures each year with no scalability.
