stochastic sorting...

[chris1]

hi guys, im wondering if you could tell me why this sample code doesnt work:

var stochastic = new StochStudy(14, 3, 3);
var stocharray;

stocharray = stochastic.getValue(StochStudy.FAST, 0, -5);
stocharray.sort(); <- this is the error: "stocharray has no properties"

what im trying to do is take the last 5 fast values, put em in an array and sort that array so i easily can get the highest / lowest "stochastic fast" values cause i need em in an calculation. i hope "stochastic fast" means the fast line not stochastic indicator fast version...

would be glad if you guys could help me out!

If I wanted the hi/lo of the stoch array, I would look at java command Math.max or Math.min

or even

for(i = 0; i < Length; i++) {
if(i == 0) {
hh = stochastic.getValue(StochStudy.FAST, 0, -i);
} else {
hh = Math.max(hh, stochastic.getValue(StochStudy.FAST, 0, -i);
}
}

thanks for the help, i was hoping to use sort cause you need less code. then you use array[0] for min or array[lenght] for max value. but since it doesnt work its not a good solution but i will try yours. thanks!

sorry, dude, now ive been here for quiet some time and tried some various versions of your code and neither work. remember ... getValue(xx, 0, -5) causes to return a array but when it compares in max it should only be a number but now its an array vs a number = error.

i still cant understand why that sort function doesnt work. anyone else who got any ideas? heres anyway a sample code where i checked highs and bottoms ...

var malong = getValue("High", 0, -20);
var mashort = getValue("Low", 0, -20);

malong.sort();
mashort.sort();

this code works all fine .. but ..

var stochastic = new StochStudy(14, 3, 3);
var stocharray;

stocharray = stochastic.getValue(StochStudy.FAST, 0, -5);
stocharray.sort(); <- this is the error: "stocharray has no properties"

what does the error code mean? how come the first code works but not the second? any suggestions to solution would be appreciated

If you want to see what is going on, try


if(getBarState()==BARSTATE_NEWBAR)
debugPrintln(stocharray )

and compare to the values drawn on the chart.

Perhaps the issue wil expose it self that way.

ill try that, thanks for the tip. but ive now tried some output and:

stocharray = stochastic.getValue(StochStudy.FAST, 0, -5);

statement works. stocharray gets the right values (5 StochStudy.FAST values), but how can i manipulate stocharray? it seems like i cant use it like an array. what i want to do is to get the highest or lowest value from stocharray. my guess is that stocharray becomes a pointer. but do you know .. if my point is correct .. if theres anyway i can copy these values returned from the studygetValue into an array not a pointer to the values.

Put a null check after defining the variable

var stocharray = stochastic.getValue(StochStudy.FAST, 0, -5);
if(stocharray == null)
return;
stocharray.sort();
debugPrintln(stocharray);

and you should no longer get any errors

thanks alexis for the help. but ive now solved it but in another way...
