volatility is very important- All my studies say that higher volatility stocks move more on a signal. Use this as an input file- and see how it works:
Most of this is derived from work by - of course- Bob Jagow
I changed it to 89 days from 21-
Play around with the if values on the ATR ratio- also play around with revenue growth which I have remmed out below.
This is the most important thing I learned this year--- oh except for relearning " the trend is your friend":
output = "atr89.lst";
issuetype common;
ProcessMS = "c:\meta\atr89\",VMS;
float cl, ATR89, tr,MA89Cl;
integer bar, testbar;
testbar:= 0; // testbar:= -30; would give ATR89 30 days ago
DaysToLoad = 91-testbar;
DaysRequired = 91-testbar;
if close(testbar) >4.99 then
if movavg(testbar,34,vol)>250000 then
//if qtrrev(0) > 1.15*qtrrev(-4) then
ATR89:= 0; // initially set it to zero for each symbol
for bar = testbar-88 to testbar do // 89 values; don't need to specify step 1 because it is the default
cl:= close(bar-1); // close(-88) to start
tr:= range(bar); // the usual case, no gap
if cl > high(bar) then //down
tr:= cl - low(bar);
else
if cl < low(bar) then //up
tr:= high(bar) - cl;
endif;endif;
ATR89:= ATR89 + tr; // add tr to previous value
next bar;
ATR89:= ATR89/89; // divide the sum by 89
MA89Cl:=movavg(testbar,89,cl);
if ATR89/MA89Cl*100>5.5 then
println symbol,",",date(testbar),",",ATR89/MA89Cl*100:6:2,",",qtrrev(0),",",qtrrev(-4);
endif;endif;endif;//endif; |
