Common trading mistakes
A frequent mistake is entering a market before deciding what would make the idea invalid. Without an exit condition, a temporary loss can become an open-ended commitment driven by hope rather than evidence.
Position size is equally important. A reasonable idea can still cause disproportionate harm if too much capital is concentrated in it. Decide the acceptable loss first, then set the position rather than starting with the possible profit.
Other recurring errors include reacting to headlines without checking liquidity, changing settings after every small movement, confusing a short positive period with a durable edge, and using money needed for essential expenses. A written process helps make those behaviours visible.
Automation can apply rules consistently, but it can also repeat a flawed rule quickly. Review alerts, connection permissions and results instead of assuming that an active system needs no supervision.
