Not really truly "understand" candlestick charts. Easiest start was C. When I realized long bullish candles show momentum (honestly, sometimes it's still intuition). Uncertain on Doji.
Too quick to take some profits but no chance to buy back on dips. Lesson learnt is to have holding discipline with the potential stocks got on watchlist.
Yes, important lesson: getting the direction right does not automatically translate into profits. Position sizing and holding discipline ultimately determine whether returns can truly be realized.
