Your decisions must be based on the chart. If you constantly watch your P&L during a trade, or get caught up in other traders’ opinions and arbitrary predictions, you’ll only grow more anxious. You might close positions prematurely out of fear of losing profits instead of waiting for your rule-based take-profit level, or you might refuse to cut losses at your stop-loss point, clinging to the hope that the price will recover. Do not let noise outside the chart sway you. All you need to do is follow the chart and your rules.
