Pyhton 股票回測繪製BBand與爬蟲

繪製BBand與爬蟲

---

技術指標用的好，也要批量選股，我們先來看初步繪圖成果吧新增了選擇檔案，稍微改了一下介面，等等批量股票篩選（暫不小心用太多執行續被官網鎖IPQQ

BBAND.py

	BBand=get_BBand()
	BBand_up=[float(x) for x in BBand [0]]
	BBand_sma=[float(x) for x in BBand [1]]
	BBand_down=[float(x) for x in BBand [2]]
	BBand_mid=[]
	BBand_width=[]
	for x in range(0,len(BBand_sma),1):
	BBand_mid.append((BBand_up[x]+BBand_down[x])/2)
	for x in range(0,len(BBand_mid),1):
	BBand_width.append(100*((BBand_up[x]-BBand_down[x])/BBand_mid[x]))

像我想爬近三個月的成交量異常！？的股票，爬下來在分析再串自動下單！？，當然也要夠本，交易策略濾網要非常嚴謹，就可以放在家自動交易！？（後果不負責xd

多執行緒下次調１０個好了，這次不知道要被鎖幾天，被當成ddos囉

換連手機一下

快像了快像了

下次目標

假設經過一票海選後，像是成交量阿還是要搜尋什麼類型的技術指標阿等等等等，我們可以把爬蟲後的資料，下再下來或倒入資料庫，下次爬蟲的時候我們只要爬，最近一筆再把他家進資料庫，這樣就可以下次不必再依賴yahoo資料庫，直接對自己資料庫要資料，我們不只可以用tick來做高頻交易（還要串ａｐｉ交易，你相信中華電信的網路嗎xdd，等等打造一個看盤軟體，或向xq操盤大師那樣什麼策略警示，等等，至於資料量的多寡，恩恩自己去爬吧xd ，接下來我們初步就完成一個最最最最基本的自動交易軟體的雛型囉，那麼ai真的真的真的要要來看一下囉，ㄎㄎ我會不會被一堆賣課程的針對‵，應該不會它們應該更有技術含量！
