$NOT The ideal time to buy and sell based on the KDJ indicator may vary depending on your trading strategy and the specific asset you are analyzing. However, here are some general guidelines:
Buy (buy signal):
When the K (fast) line crosses above the D (slow) line, this can be considered a buy signal.
In addition, if the J (smoothing) line is also rising, this can reinforce the buy signal.
Sell (sell signal):
When the K line crosses below the D line, this can be considered a sell signal.
If the J line is also falling, this can confirm the sell signal.
