Hi Tony
My mistake, first for not testing it as I should have, and second, for setting the number of bars to
63 instead of 130 (3 months approximation instead of 6 months). this appears to work OK. I can't
think how I managed to turn 6 months into 3 months :-(
Signal:=4*(Std(C,20))/Mov(C,20,S);
Signal=LLV(Signal,130);
Here's a test indicator you can create for checking the signal, the lowest signal low for the past
six months, and whether the signal is currently equal to that lowest low (true or false). The
look-back is not exact but you can fiddle the numbers to whatever is most appropriate.
{Test Indicator}
Signal:=4*(Std(C,20))/Mov(C,20,S);
Signal;
LLV(Signal,130);
Signal=LLV(Signal,130);
My testing suggests you should get around a 2% hit rate. I got 6 current hits off the ASX S&P 300,
and the same ratio when going back over two years of data.
Kind regards
