My version of the 3-13ema cross.
The oscilators are essentially MACD for multiples of the 3 and 13 ema's. They represent, as near as possible, the 3-13ema's on the next trend direction TF up and, for good measure, the one above that.
That is 15/h1/h4 or h1/h4/daily
It seems to work well.
It saves a lot of clicking through different timeframes and is automatically updated if looking for trades on say, the 15min and 1 hour.
