Hasil operasi:

Nota: Apabila bot strategi berjalan di halaman bot, jika anda menggulir melalui rekod sejarah, bar status akan memasuki keadaan tidak aktif dan berhenti mengemas kini. Data bar status hanya akan menyegarkan apabila log berada di halaman pertama. Bar status menyokong output imej dikodkan dalambase64, dan juga menyokong output imej dikodkan dalambase64Kerana panjang rentetan imej yang dikodkan biasanya sangat panjang, tiada kod sampel diberikan.

EnableLog ((()

EnableLog(IsEnable)menghidupkan atau mematikan rakaman log untuk maklumat pesanan. Nilai parameter:isEnableadalah jenis bool. JikaIsEnableditetapkan kepadafalse, log pesanan tidak akan dicetak dan ia tidak akan ditulis ke pangkalan data bot.

Chart(...), fungsi untuk menyesuaikan gambar carta.

Chart({…}); parameter ialahHighCharts.StockChartparameterHighStocksyang boleh diserialisasikan dalamJSON, dengan menambah_isStockattribute kepada parameter asli. Jika anda menentukan_isStock:false, ia akan dipaparkan sebagai carta biasa.

Nota: Jika anda menetapkan sifat_isStockkepadafalse, carta yang digunakan ialah:Carta tinggi, seperti yang ditunjukkan dalam carta:

Jika kita menetapkan atribut_isStockkepadatrue, carta yang digunakan ialah:Stok tinggi(default)_isStocksebagai benar), seperti yang ditunjukkan dalam carta:

Untuk kembali ke objek, anda boleh memanggiladd(n, data) (n(seperti 0) adalah indeksseries, dandataadalah data yang ditulis dalam carta) untuk menambah data kepada indeks yang ditentukanseries; panggilanreset()untuk membersihkan data carta, danresetboleh mengambil parameter berangka dan menentukan bilangan item yang disediakan.

Kamu boleh hubungiadd(n, data, i) (iadalah indeks data ini dalamseries) untuk mengubah data dalamseries.

Ia boleh menjadi negatif, -1 merujuk kepada yang terakhir, dan -2 adalah yang kedua terakhir.

chart.add(0, [1574993606000, 13.5], -1), menukar data titik terakhirseries[0].data.

Untuk ia menyokong untuk memaparkan pelbagai carta, anda hanya perlu lulus dalam parameter array semasa konfigurasi, seperti:var chart = Chart([{…}, {…}, {…}])Sebagai contoh, carta 1 mempunyai duaseries, carta 2 mempunyai satuseries, dan carta 3 mempunyai satuseries. Kemudian, tentukan siri ID 0 dan 1 apabila menambah mewakili untuk mengemas kini data dua barisan urutan carta 1; tentukan siri ID 2 apabila menambah merujuk kepada yang pertamaseriesData; menentukan siri ID3 merujuk kepada data yang pertamaseriesdaripada carta 3.

• cfgA.extension.layoutatribut

  Jika atribut ini ditetapkan dan nilainya adalah single, carta tidak akan bertindih (ia tidak akan dipaparkan sebagai label tab) dan akan dipaparkan secara berasingan (penampilan berpayung).

• cfgA.extension.heightatribut

  Atribut ini digunakan untuk menetapkan ketinggian carta.

• cfgA.extension.colatribut

  Atribut ini digunakan untuk menetapkan lebar carta. Lebar halaman dibahagikan kepada 12 unit secara keseluruhan, dan menetapkan 8 bermakna carta menduduki 8 unit lebar.

• Untuk data pada objek konfigurasi carta, mengubah suai konfigurasi carta secara langsung, dan kemudian mengemas kini carta untuk merealisasikan kemas kini data:

  Sebagai contoh, dalamJavaScriptBahagian kod contoh (Contoh Lengkap):

  cfgC.series[0].data[0][1] = Math.random() * 100
  cfgE.series[0].data[0][1] = Math.random() * 100
  // "Update" is actually equivalent to resetting the configuration of the chart

Operasi lukisan dijalankan dengan melintasi data K-garis. Operasi lukisan mesti bermula denganc.begin(bar)panggilan fungsi dan berakhir denganc.close()panggilan fungsi. fungsi antara muka lukisan bahasa Pine yang disokong dalam operasi lukisan adalah:

• Barcolor: Set K-line warna

  barcolor ((warna, offset, boleh diedit, show_last, tajuk, paparan)

  c.barcolor(bar.Close > bar.Open ? 'rgba(255, 0, 0, 0.2)' : 'rgba(0, 0, 0, 0.2)')   // Use the example illustrated in the reference code in this example, without giving unnecessary details

  • displayparameter pilihan: tidak ada, semua

  SejakJavaScriptbahasa tidak boleh menentukan parameter masuk mengikut nama parameter formal fungsi, untuk menyelesaikan masalah ini, a{key: value}struktur boleh digunakan untuk menentukan parameter yang dilewatkan dalam nama parameter rasmi tertentu, contohnya dalam kod rujukan, penggunaan{color: bar.Close > bar.Open ? 'rgba(255, 0, 0, 0.2)' : 'rgba(255, 0, 0, 0.2)'}untuk menentukancolorparameterfillJika anda perlu menentukan parameter dengan beberapa nama parameter berturut-turut, anda boleh menggunakan{key1: value1, key2: value2, key3: value3}. Sebagai contoh, dalam contoh ini, menambah parameter yang menentukantitle: {color: bar.Close > bar.Open ? 'rgba(255, 0, 0, 0.2)' : 'rgba(255, 0, 0, 0.2)', title: 'fill'}.

  Untuk nilai warna, anda boleh menggunakan'rgba(255, 0, 0, 0.2)'kaedah untuk menetapkan, atau menggunakan'#FF0000'kaedah untuk ditetapkan.

LogReset()

LogReset()log yang digunakan untuk membersihkan log. anda boleh lulus dalam parameter bilangan bulat untuk menentukan bilangan log baru-baru ini untuk mengekalkan, dan membersihkan baki log. log permulaan dikira setiap kali ia dimulakan, jadi jika tiada parameter yang diteruskan, dan tidak ada log output pada permulaan strategi, log tidak akan dipaparkan sama sekali, menunggu log docker untuk kembali (bukan keadaan yang tidak normal). fungsi ini tidak mempunyai nilai balik.
