There is no leading indicator, not even Price, TA represents the past but so does charting, but tests base on history and out of sample back testing either shows high/low probabilities of possibilities for the future. You can have a 99.99% probability of price going to do "X", and if it doesn't, "Y" is produced.
We make predictions on every single trade.
"1) Find a trade that you believe will have a positive expectancy
2) Don't listen to what
@Buy1Sell2 is saying
3) Manage your risk based on already documented and public theories."
Any trade that I hedge has positive expectancy, that is not to say I won't have losses, there is nothing in mankind, with exception of death, that is 100%. In 2010, I changed my style of trading to Risk Management first and profits second, it has made my equity curve much more stable, more stable means more size and confidence. Where I once would disagree with B1S2, I now agree. Why would anyone want to manage risk with the masses? This makes no sense to me at all, find a different way than the masses.
People don't know expectancy of their trades as risk management is not much of an important part of their methods, until it is to late. It is similar to studying dozens of systems that under funded traders would be doing to know where they place there protective stops, so when volume forces price in that direction to trigger stops, that is the time to hop on board. When under funded see the market going in their intended direction, it is generally too late to be getting in, but they help push market to go further and volume be going other way. LOL
Longer I stay in trading, I find where I get in means less, rules in place base on time management and options(risk Mgt). Good entries are a fluke, profits have an unknown, risk is controlled to fair degree.
To those who don't know how to program so you can back test, hire someone, as markets become more and more professional, more automated, going to be tougher for under funded traders. Have to know the stats, otherwise be like song "Dust in the Wind".
