Looking for 100 or even 400:1 leverage and trying to make 20-100% a day is all wrong, it just won't work, period!
**************************
No any scientific evidence Sir
1 question - did retail operator have any edge ?
To win in long row of 1000 operations with risk -reward 1:1 more as 500 operations
(520-550-600) .You can recalculate for another
risk -reward relations
If retail have not any advantage(this point of view support author) ,than your statement have not any scientific value
If you wish acuire scintific point of view ,
read A.Puankare,J.von Neumann, Shannon ,Kelly about game theory
Market -maker have advantage he taked
each day more as 100 spread to he's profit
Market -maker by Goldman Sachs 30 years old VP -1-1.15 mln $ per year
Senior parnter (Goldman have some 200)
35 years 5 mln $ per year .
Win as 2-5 mln $ in 5-10 years in retail sector is occasion comparable with lotto .
Best wish ...
