I don't use indicators, they're not my style, they lag, they repaint; and in my opinion they don't work.
The 200 EMA on DAILY can be useful because of how slow it is. We can use it to filter the direction of which way we trade.
Price ABOVE 200 ema = ONLY BUY
Price BELOW 200 ema = ONLY SELL
Then drop timeframes for your entries via your strategy whatever that...
Simple indicator which paints the same EMA twice (default to 20), one set to open one set to close. The idea being the when the price is closing > the open on average number goes up.
Green on top trends up, red on top trends down. Only really backtested this on HTFs, works well on daily, interesting on weekly but you lose a lot of wicks.
Try it with the candles hidden.
The DXY being weighted as follows:
EUR - 57.6%
JPY - 13.6 %
GBP - 11.9%
CAD - 9.1%
SEK - 4.2%
CHF - 3.6%
As you may imagine, there's a lot more interest in using the DXY for a correlation / confluence tool when trading the EURUSD . The EURO equates to over half of the overall weight of the index, meaning there's a majority interest in the EUR vs USD.
