Van Tharp, for anyone wondering, wrote "Trade your way to financial freedom" and "super trader", which cover the basics of trading systems and getting the human factors under control. Reading his books really burst my bubble of expecting I could predict the future and bet the farm, every trade. I had absoutely no clue about expectancy, max drawdown, position size, or even basic risk management before reading the first one. Highly recommended!
Scalping is for the minimum tick size. No one effectively scalps from the outside. Rather, I think what you mean is very short term trading and are using the term "scalping" incorrectly.
I count break even (+/-1 tick plus commission) trades separately from losing trades (up to 1R plus a bit of slippage plus commission) and fuck-up trades (considerably higher than 1R due to whatever - years ago moving the stop, etc., in the last few years usually from slippage due to putting on trades right before news/reports that I should have been aware of). Last year I had over 50% BE trades - and doubled my trading account (which is great but kind of sucks vs. say just buying and holding Nvidia or Tesla or Palantir or whatever with way less work) with a ridiculous low amount of risk and drawdown (which probably means I'm a pussy and I'm way under-leveraged ). Personally, I don't care about % of winners or losers or be's as long as my expectancy is positive. But then again my approach is life-changing growth, however irregular, not steady income. But hey, to each his own according to their personality, etc.
I did this years ago, it was recommended by Dr. Steenberger in The Daily trading Coach if I recall correctly. Lots of work. Useful for some aspects, but also easy to miss the forest for the trees. You don have much to lose except time and effort, so I'd give it a try for a couple of weeks and see if it's useful *to you*.
I've travelled on all budgets, from backpacker's dorms to Maldives villas, and I've always seen the same set of people everywhere: the happy, the angry, the sad, the bickering, the lovely... No relation to their budget or profession or studies... It was always about the company (the people ) they kept. Kind of obvious, yet not so obvious to many it seems.
