function loadTop() {
$webServicesFactory.get($marketProvider[$scope.currentMarket].topGetURL, {AnonymousToken: $marketProvider[$scope.currentMarket].token}).then(
function success(response) {
$scope.top = response.Stock.slice(0, 10);
$scope.low = response.Stock.slice(10, 20);
console.log($scope.top);
loadStockCount();
loadTop();
loadLow();
$ionicLoading.hide();
},
function error(error) {
$ionicLoading.hide();
}

var numStocks = response.Stock.length;
var halfStocks = Math.round(numStocks / 2);
$scope.top = response.Stock.slice(0, halfStocks);
$scope.low = response.Stock.slice(halfStocks, numStocks);
