TradingView 初识

發(fā)布時(shí)間：2023/12/19 综合教程 23 生活家

生活随笔收集整理的這篇文章主要介紹了 TradingView 初识小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

如引用 TradingView 庫，需引入庫中 3 個(gè)文件（所需庫為 github 私有庫，需申請(qǐng)）

<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>

初始化圖表：

    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, //需要顯示的數(shù)據(jù)內(nèi)容
            disabled_features:[
                //'volume_force_overlay',// 成交量與k線分離
            ],
            overrides:{
                'volumePaneSize': 'small', //成交量高度設(shè)置，可選值 large, medium, small, tiny

            }
        });

我也不知道這是加載圖表還是什么，反正就出現(xiàn)圖表了

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",
                "pricescale": 500,
                "minmov": 1,
                "ticker": 'D',
                "description": "DIdontKnow",
                "session": "24x7",
                "type": "bitcoin",
                "has_intraday": true,
                "intraday_multipliers": ['1', '30', 'D'],
                "has_weekly_and_monthly": false,
                "has_no_volume": false,
                "regular_session": "24x7"
            });
        }
            

        return new Datafeeds.Container;
    }

數(shù)據(jù)內(nèi)容為自己設(shè)置的隨機(jī)生成的一些數(shù)據(jù)，僅供測(cè)試使用

    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);
    }
