so here are my thoughts..... im sure we are all aware of the 'classical' trading texts. they all seem to have this concept of risk management & position sizing theories of only risking 2% of the account. all these theories however seem to be based around long term trend following - like its the only game in town. i believe most day traders then take this theory up - one of the reasons why few succeed. they just grind their account down. then i start to investigate how TODAYS big successful DAY traders go about their business. (harris brumfield, paul rotter etc) NONE of these guys seem to advocate such small %. they seem to take the approach that if they are right, they want to be right in a big way. large traders i know personally also have a similar approach. suggest to them only risking 2% and see how hard they larff!! side splitting. the theory for day trading that i have recently taken on is to be do as big a size as i can afford to take, given my recent performance (direction of my equity curve & win rate!). if i take a few hits i scale back. if i take a few wins, i double my size again. i am a discretionary trader however. i only take positions when i am sure. i acknowledge that if you decide to trade on a 100% mechanical basis or use an automated system, are active in many markets at once (i.e. playing a numbers game rather than specialization in 1 or 2 markets) that a tiny % could be a good idea. who has similar ideas to me? who thinks i wont be here in 6 months?
