Good work martin, nice to find some EMA's that suit your trading style. I use a few EMA's as well but at the end of the week when I review my trading, is was price action setups that were my correct trading signals.
I use the 240 EMA on H4 because it is actually the Weekly EMA10 which gives me Bias.
Therefore I believe you are trading close to how I trade
POWER OF THE 10EMA
MOVES BELOW WEEKLY 10EMA (H4 240EMA) - Bias is Short - Start building a basket of Short trades
