Donchian channels: the breakout indicator the Turtles got rich on
Two lines — the N-bar high and the N-bar low — and a rule to enter on breakouts. That's a Donchian channel. The system trained the most famous prop-trading class in history. Here is how it works and where it breaks.

Bid-ask spread: the cost everyone pays and most traders ignore
Every trade has a hidden tax that gets paid the moment you cross the spread. On low-volume strategies it's negligible; on anything frequent, it's the single largest cost — and most retail backtests pretend it doesn't exist.

What is a trend? The Dow-theory answer that most retail traders skip
