"we wait for the candle to touch ema 50, "
Candle high above EMA 50.
"then we open a 65 pip sl /tp sell transaction"

"if the color of the new candle opened after the candle is touched is red"
touched candle is a bear candle
"and the candle ema is below 50."
candle is below ema 50.
if this is not the case, redraw your picture to show where you need to wait and specify how long you want to wait....or perhaps theres some other logic that you're looking for.
