And here is yet another fast version, which eliminates the convoluted close(i+j), and puts the j loop within the i loop. This was suggested by someone in e-mail, and it's a much better way of doing it, I think:
//Shark-32, by Walter T. Downs,
//translated for QP2
output = "sharka.lst";
input="volvol.lst";
//ProcessMS = "d:\meta\macdup\",VMS;
integer i, j;
float shark, apex, WB, fin, sharkhigh, symmetry;
for i = -24 to 0 step 1 do
symmetry:=.28;
apex:=(high(i)+low(i))/2;
WB:=range(i-2);
if apex<=(high(i-2)-(WB*Symmetry)) and
apex>=(low(i-2)+(WB*Symmetry)) then
fin:=1;
sharkhigh:=0;
if high(i)<high(i-1) and
low(i)>low(i-1) and
high(i-1)<high(i-2) and
low(i-1)>low(i-2) then
shark:=fin;
if shark=1 then
sharkhigh:=high(-2+i);
endif;
if shark=1 then
if sharkhigh>0 then
for j = i to 0 step 1 do
if close(j)>sharkhigh then
if close(j-1)<sharkhigh then
println symbol,",", "Close: ", close(0):6:2,", ", "Change: ",
Close(0)-Close(-1):5:2, ", ", "Date: ", date(j),
", ", "Sharkhigh: ", sharkhigh; //date of buy signal
j:=0;
endif; endif;
next j;
endif; endif;
else
shark:=0;
endif;
else
fin:=0;
endif;
next i; |
