新宝塔线指标源码
所谓右侧交易者是指等趋势.图形和价格变动以后才操作的人,右侧交易者从不预测后面会怎么样,只做现在该做的事。不受周边环境的影响,客观理智的跟随走势而行动。新宝塔线的特性就是很适合右侧交易者的工具。
对技术指标,大家要有理性的认识.因为它们大多是以价格或量为基础而编写的.这就决定了它的滞后性和可改变的随意性.既不是万能的,也不会有100%准确率.但是,做为市场弱势群体的小散,指标却又是偶们唯一能简单上手的武器,那怕就是根木棍也比赤手空拳好些吧!
对于偶来说,偶认为指标的最大定义是:能用简单的方法找到股票上涨或下跌的共同性。如:“股票上涨或下跌,必会上穿或跌破5日均线。”虽说有了共性也不见的就会走出一样的走势。可是这毕竟增大了操作的概率的胜率。当配合基本的量能和K线上的共性后,胜率不是就大的多了吗?有些朋友进入股市,喜欢研究各式各样的指标公式。到最后却因为掌握了太多的武器,事到临头反而不知道使用那种武器好了,所以会千种不如精一门。
好的指标公式只要有两个功能就可运用于实战,配合量能,K线,加上一些资金的管理运用,你就可以在股市多赚少亏。
第一个功能是能确定股票现行的方向。
第二个功能是可以轻松的找到买卖点。
而新宝塔线就具备这样的两大功能。
方向:价在多空线上,多空线紫色该股现在正处于上行趋势,入场操作。
价在多空线下,多空线蓝色该股现在正处于下跌趋势,场外观望。
买卖点:三平底买进,三平顶卖出。黄托底买进,绿压顶卖出。配合XMA线 使用。宝塔线分析要点;(1)宝塔线翻红之后,股价后市总要延伸一段上升行情。(2)宝塔线翻青之后,股价后市总要延伸一段下降行情。(3)盘局时宝塔线的小翻红,小翻青,可依设定损失点或利润点之大小而决定是否进出。(4)盘局或高档时宝塔线长青而下,应即获利了结,将手中持股卖出;反之,翻红而上,则是介入时机。(5)宝塔线翻青下跌一段后突然翻红,须防范为假突破之现象,不可马上抢进,须察3天。【均K线组合规则】★宝塔线红色且5天均线上行,看多做多(可追多,不惜帮庄家抬轿)★宝塔线红色但5天均线走平或下行,看多不做多(有筹码的继续与狼共舞,没筹码的观望不进)★宝塔线绿色且5天均线下行,看空做空(对准接盘杀跌,不计盈亏)★宝塔线绿色但5天均线走平或上行,看空不做空(没筹码的观望不进,有筹码的即使套牢也暂不割肉)。这样操盘心态极佳。【宝塔线指标用法】黄托底买进。绿压顶卖出。宝塔线1MA:ma(c,5),COLORWHITE;
