Bollinger Band Red(50,2)
BB yellow(50,3)
BB dark orange(50,4)
RSI(3)
Random(6,3,3)
EMA100 white
EMA200 lime purchase:
Wait for price to break out of the lower red BB, RSI less than 20, and Stoch less than 20. If the price returns to the red line, RSI > 20, and Stoch reaches or exceeds 40, we open a long position after the close of the candle.
SL: Yellow or dark orange lower BB, depending on your risk tolerance.
TP: BB center line (50SMA) or upper red BB
sell:
Wait for the price to break through the red BB above, RSI>80, stoch>80. Wait for the price to return below the red line, RSI below 80, and Stoch to 60 or below to open a short position.
SL: Upper yellow or dark orange BB
TP: Midline or upper red BB
Note: If EMA 100 and/or EMA 200 is inside the red BB, it is better not to trade, or use it as TP if R:R is suitable.
