Donald Pendergast's article, “Swing Trading with Three Indicators” presented an easy to understand trading system. The template is easy to create for visually scanning charts but is not as helpful with large groups of trading candidates. The formulas below can be used to create explorations, an expert advisor, and/or a system test:

Buy:

incr:= 0.05; {amount above/below bands for entry signal}

H > Mov(H, 5, S) + incr AND C > Mov(C, 50, E)

Sell:

L < Mov(L, 5, S)

Sell Short:

incr:= 0.05; {amount above/below bands for entry signal}

L < Mov(L, 5, S) - incr AND C < Mov(C, 50, E)

Cover:

H > Mov(H, 5, S)
