Fibo retracement is to measure retracement, so what I look for is a candle that shows at a level a sign of tiredness. I look for something like a pinbar, a fake out, an inside bar (and break), a morning star and whatever suggests tiredness, like a congestion forming above or below a fib level. I think further indicators like the listed oscillators might not be necessary. But don't take my word for it, I really don't like oscillators except when I do M5 scalping that involves MACD.
