  • TradingView 初识

    如引用 TradingView 库,需引入库中 3 个文件(所需库为 github 私有库,需申请)

    <script type="text/javascript" src="/static/charting_library-master/charting_library/charting_library.min.js"></script>
    <script type="text/javascript" src="/static/charting_library-master/datafeeds/udf/dist/polyfills.js"></script>
    <script type="text/javascript" src="/static/charting_library-master/datafeeds/udf/dist/bundle.js"></script>

    初始化图表:

        TradingView.onready(function () {
            var chart = window.tvWidget = new TradingView.widget({
                symbol: 'd',
                height: '900',
                 '1700',
                interval: 'D',
                toolbar_bg: '#c5c5c8',
                timezone: 'Asia/Shanghai',
                time_frames: [
                    {text: "1y", resolution: "1W"},
                    {text: "6m", resolution: "3D"},
                    {text: "3m", resolution: "1D"},
                    {text: "1m", resolution: "1D"},
                    {text: "1w", resolution: "30"},
                    {text: "3d", resolution: "30"},
                    {text: "1d", resolution: "30"},
                    {text: "6h", resolution: "15"},
                    {text: "1h", resolution: "1"},
                    { text: "100y", resolution: "W", description: "All", title: "All" },
                ],
                container_id: 'tv_chart_container',
                library_path: '/static/charting_library-master/charting_library/',
                locale: 'zh',
                //datafeed: new Datafeeds.UDFCompatibleDatafeed("https://demo_feed.tradingview.com"),
                datafeed: chart_data, //需要显示的数据内容
                disabled_features:[
                    //'volume_force_overlay',// 成交量与k线分离
                ],
                overrides:{
                    'volumePaneSize': 'small', //成交量高度设置,可选值 large, medium, small, tiny
    
                }
            });

    我也不知道这是加载图表还是什么,反正就出现图表了

    function createChartData(){
            Datafeeds.Container = function () {
                //this._configuration=configurationData
                this._configuration = {
                    supports_search: false,
                    supports_group_request:false,
                    exchanges:[{value: 'DV', name: 'NYSE', desc: 'DeVry Education Group Inc.'}],
                    supported_resolutions: ['1', '15','D','M'],
                    supports_marks: false,
                    supports_time: false,
                    supports_timescale_marks: false,
                    symbols_types: [{name: 'Ny', value: 'dv'}],
                }
            }
            Datafeeds.Container.prototype.onReady = function (callback) {
                let that = this;
                getChartData();
                if(this._configuration){
                    setTimeout(function(){
                        callback(that._configuration);
                    }, 0);
                }
            }
    
            Datafeeds.Container.prototype.getBars = function(symbolInfo, resolution, dataFrom, dataTo, onHistoryCallback) {
                onHistoryCallback(dataBar);
    
            }
            Datafeeds.Container.prototype.resolveSymbol = function(symbolName, onSymbolResolvedCallback, onResolveErrorCallback) {
                onSymbolResolvedCallback({
                    "name": 'D',
                    "timezone": "Asia/Shanghai",

                    "intraday_multipliers": ['1', '30', 'D'],
                    "has_weekly_and_monthly": false,
                    "has_no_volume": false,
                    "regular_session": "24x7"
                });
            }
                
    
            return new Datafeeds.Container;
        }

    数据内容为自己设置的随机生成的一些数据,仅供测试使用

        function getChartData() {
             var time = 1528404420000;
             var maxHigh = 8888;
             var minLow = 8000;
             for (var i =0; i<10000; i++){
                 var high = maxHigh - Math.floor(Math.random()*300);
                 var low = minLow + Math.floor(Math.random()*300);
                 var close = high - Math.floor(Math.random()*500);
                 var open = low + Math.floor(Math.random()*500);
                 var volume = parseInt(Math.random()*100);
                 this.dataBar.push({
                         time:time,
                         close:close,
                         open:open,
                         high:high,
                         low:low,
                         volume:volume
                     })
                 time += 2000000;
             }
            //console.log(dataBar);
        }
