If I may chime in here....
grow his account and trades, and compound the overall process.
Compounding is, truly, the 8'th Wonder of the World,
Trade 1....100
Trade 2 ....200
Trade 3....400
Trade 4....800
Trade 5...2000
Trade 6....4000
Trade 7....8000
Trade 8....20000
Trade 9....40000
Trade 10....80000
Trade 11....200000
Trade 12....400000
Trade 13....800000
Trade 14....2000000
The skill, rarity, mastery, of course...is being relatively consistent and able to pull off those, winning, trades. And not many people have these traits, mindsets, and understandings to accomplish such a feat.
