周末有位一又友问起Heikiun Ashi筹画，那时在外地没怎么回应，今天在这里与公共一齐共享文采版与MT4版源码的不同，有利思意思学编写筹画的一又友一齐来考虑下。
Heikiun Ashi筹画Heikiun Ashi筹画称平均棒图或平滑烛炬图，通过计较每个时刻周期的开盘价、最高价、最廉价和收盘价，生成新的烛炬图，以更了了地展现价钱趋势。这种筹画有助于过滤市集杂音，突显主要趋势，提倡用于大周期看趋势。Heikiun Ashi筹画并不提倡单独动作期货、外汇大略黄金的往复有筹画的依据，投资者应当与其他技巧分析筹画、基本面分析和市集情谊等身分汇聚拢，进行概括判断。图片

源 码 下方共享的Heikiun Ashi筹画源码为主图K线款式，是字据常见的面目改写。仅动作战略念念路拓展，不提倡径直用于期货等投资实盘中（投资有风险，入市须严慎）。往复员不错字据艾云战略所提供的筹画源码，聚拢频频的往复训诲进行改编，造成我方的往复战略。文采版：适用于文采6、7、8等软件
