I like to use the attached indicator on a chart, opened two times, f.e. small line with 100 (length in bars) and big line with 150 (length in bars).
A trading signal appears when both lines are crossing each other. Now I need an indicator that gives alert (pop-up window, sound and eMail)
at this crossing point. A buy-signal (arrow up) means small lines crosses big line from below to above; a sell-signal (arrow down) means
small line crosses big line from above to below. to make this clear I also attached (no 2) an alert-indicator for ma- lines on mt4-plattform.
