As an award-winning #1 rated readers choice columnist for TASC magazine, and former statistician for Ford, here's my .02:
Price action, trading ranges and risk management is more important than any squiggly lines on charts.
The math is far more important than charts, x100 when it comes to making money trading.
Knowing trading ranges/ATR and trading with position sizing is essential.
Using 50 100 200 sma on daily charts is useful to know what the herd is following.
Candle patterns esp hammers work often.
In training thousands during 21 years, where traders screw up is:
You trade choppy narrow range charts that aren't clean, wide range.... charts under $10 are for morons
You undertrade, waiting for a few great looking breakouts or pivots and still lose
Your stops are way too costly, mine are almost always under $70 max
So much more, there's a lot of fixes
