buy when you get a buy signal and sell when you get a sell signal. if the candle passes sell signal then yoou have to buy again and sell at the next sell.
SYN is a fine example how our buy got detected on a bullish sentiment and you can see now buy anywhere and it's happeing on a 15 min candle
I recommend the next buy if there is a break at 0.95 and above.
