Scalping defined.
Last traded price = the most recent assesment of a price where trade will take place. ( the market's function after all!)
Selling on the offer= a miniscule edge on this value price
Buying on the bid= a miniscule edge on this value price.
Expanding beyond the tic scale, the control price on yesterday's value bellcurve= the most valued price
Selling 2sd above this price= an edge on value if the current distribution holds and a low risk exit if it doesn't
Buying 2sd below this price= an edge if the current distrribution holds etc....
This type of scalping must always be undertaken with a mind to the current trend in daily value......Obviously!!
I'm just trying to outline basics here...If you want the meat, then go and do your homework. These are the basic rules, exceptions must be learnt, as in any language.
The bigger the timeframe you can handle, the more stable will be the market's output and assesment of value. In other words, the longer your time frame, the less bullshit, volatility, noise, bollocks, etc.... you will have to contend with in your decision making.
The truth is out there.
