- Reading the screenHow to read a candlestick chartEach candle packs four numbers into one shape: open, high, low, close. Learn the body, the wicks, and what a long wick is actually telling you.
- What it costsThe spread: why you start every trade behindThere are always two prices, and you cross the gap twice per round trip. Why commission-free is not free, and where the spread gets expensive.
