ADX & MA Signals

Postby Alexander.Gettinger » Mon Apr 26, 2010 3:27 pm

Trading Strategy Algorithm:

1. Open a daily chart for EURUSD, lots 0.1.

2. Draw an ADX with the period of 14, mark level 20 in the indicator.

3. Draw an MA with the period of 21.

Buying signal: The bar closes above MA, and the ADX line is above 20.
Selling signal: The bar closes below MA, and the ADX line is above 20.

Hi Avignon,

Is this a strategy or just a signal?

Just signal.

AMHA, to limit false signals, you expect the trade signal in daily but will switch to lower UT to place your order. So you will be sure to be in the trend. ;)
