Requirements:
A pebble watch, tasker, android phone, and canvas. You should have some basic knowledge of these. Not hard just takes a bit of learning.
Note that the web call uses bitcoinaverage.com api vs. bitstamp api.
In tasker:
Add Net http get: to the web page of the bitcoinaverage.com api.
Add Script JavaScript: Set the path to your saved javascript file
Add Plugin> Pebble Notifier: Add notifier to "BitStamp"
You can change the percentages for the + and - as you see fit.
---script---
var parsebitstamp = JSON.parse(global('HTTPD'));
var err = "";
try {
var bittemp = global('BitLast');
var input= parsebitstamp['last'];
setGlobal('BitLast', input);
if (input >= bittemp)
{
var percent = 100-bittemp/input*100;
if (percent > .25)
{
var lastout = "+";
}
else
{
var lastout = "=";
}
}
if (input < bittemp)
{
var percent = 100-input/bittemp*100;
if (percent > .25)
{
var lastout = "-";
}
else
{
var lastout = "=";
}
}
setGlobal('LastOutA',global('LastOutB'));
setGlobal('LastOutB',global('LastOutC'));
setGlobal('LastOutC',global('LastOutD'));
setGlobal('LastOutD',global('LastOutE'));
setGlobal('LastOutE',global('LastOutF'));
setGlobal('LastOutF',global('LastOutG'));
setGlobal('LastOutG',lastout);
var trend = global('LastOutA')+global('LastOutB')+global('LastOutC')+global('LastOutD')+global('LastOutE')+global('LastOutF')+global('LastOutG');
var output = trend+input.toFixed(0);
}
catch(err) {
output += err;
}
setGlobal('BitStamp', output);
