Strategies are not enough. Stop trying to Predict. Observation.

Most traders rely upon an indicator signal or a strategy and when these fail they are often baffled by their loss. Losses erode capital but more importantly your self confidence.
Learn to READ stock charts. Be observant in seeing patterns developing before a stock has a huge gap up or down.
NVDA had several patterns that warned early that the stock was at risk of a big gap down. It was going to go down but the gap was far larger than most traders expected and few traders were in this stock before the huge highly profitable sell short gap down.
The reversal candle today is also surprising many traders when it was obvious that the stock had fallen below fundamental values visible in the trend and candles.
Learn how to be more observant so that you are ahead of big gaps and fast running stocks rather than chasing a stock that has already gapped and is at high risk of profit taking.
