Buys if there is crossover in J and D and the crossover is above an SMA defined as an input parameter Sells if the close is below the SMA or there is a crossunder in J and D
The KDJ calculation is done using ll21LAMBOS21 script. I added start date, end date, stop loss margin and stop profit margin to ease the simulation on diferent conditions of the market.
Tested on BTCBUSD pair. Gives good results in 30m candles with K period = 7 and D period = 3, but also works fine with K period = 14 and D period = 8. It works fine when market is bullish and gives false signals in flat markets. I just developed long strategy, as it is developed to operate in SPOT trading.
