``` javascript
|
|
var maxSpace = 0;
|
|
|
|
function adjustFloat(v) {
|
|
return Math.floor(v*1000)/1000;
|
|
}
|
|
|
|
function printCurPrice() {
|
|
for (var i = 0; i < exchanges.length; i++) {
|
|
Log(exchanges[i].GetName(),'=',exchanges[i].GetTicker());
|
|
}
|
|
}
|
|
|
|
function onTick() {
|
|
// TODO something.
|
|
var smallPrice = 99999;
|
|
var bigPrice = 0;
|
|
var curPrice = 0;
|
|
var curSpace = 0;
|
|
|

for (var i = 0; i < exchanges.length; i++) {
|
|
curPrice = exchanges[i].GetTicker().Last;
|
|
if (curPrice < smallPrice){
|
|
smallPrice = curPrice;
|
|
}
|
|
if (curPrice > bigPrice){
|
|
bigPrice = curPrice;
|
|
}
|
|
curSpace = bigPrice - smallPrice;
|
|
}
|
|
|
|
if (curSpace > maxSpace){
|
|
maxSpace = curSpace;
|
|
//打印各交易所当前的市场行情；

printCurPrice();
|
|
Log('有新高差价:', adjustFloat(maxSpace),'高价:', bigPrice,'低价:', smallPrice, '发生时间 →_→');

function main() {
|
