本書(shū)通過(guò)大量真實(shí)的股價(jià)走勢(shì)進(jìn)行實(shí)戰(zhàn)分析，向讀者介紹了各種股市行情下的個(gè)股走勢(shì)分析技巧。
全書(shū)共9 章，共計(jì)103 項(xiàng)知識(shí)點(diǎn)，內(nèi)容包括了解盤(pán)口基礎(chǔ)知識(shí)、了解盤(pán)口要素、解密盤(pán)中買(mǎi)賣(mài)盤(pán)、掌握大盤(pán)盤(pán)口、認(rèn)識(shí)K 線及形態(tài)、看懂盤(pán)面量?jī)r(jià)關(guān)系、解讀盤(pán)口的線與勢(shì)、利用指標(biāo)看盤(pán)以及分析主力意圖。通過(guò)對(duì)本書(shū)的學(xué)習(xí)，讀者可以快速掌握盤(pán)口信息，分析盤(pán)口數(shù)據(jù)，準(zhǔn)確把握市場(chǎng)行情，及時(shí)做出正確的投資決策，獲得收益。
無(wú)論是新進(jìn)股民，還是股票投資愛(ài)好者，相信都可以在本書(shū)中學(xué)到看盤(pán)的基礎(chǔ)知識(shí)以及實(shí)戰(zhàn)技法，以便在之后的投資實(shí)戰(zhàn)中從容應(yīng)對(duì)股市變化。
