重心指标
重心指标是一个震荡指标，由John Ehler发展并发表在2002年5月的股票与商品杂志上。此震荡指标不仅有很高的精确度，在指示支点（pivot point）的同时几乎不存在滞后。这个指标是研究自适应滤波器的产物。
The legend in the InstaSpot team!
Legend! You think that's bombastic rhetoric? But how should we call a man, who became the first Asian to win the junior world chess championship at 18 and who became the first Indian Grandmaster at 19? That was the start of a hard path to the World Champion title for Viswanathan Anand, the man who became a part of history of chess forever. Now one more legend in the InstaSpot team!
Borussia is one of the most titled football clubs in Germany, which has repeatedly proved to fans: the spirit of competition and leadership will certainly lead to success. Trade in the same way that sports professionals play the game: confidently and actively. Keep a "pass" from Borussia FC and be in the lead with InstaSpot!

CG = -1*NUM/DEN
NUM = int (n, i = 0) [PRICE{i}*{i+1}]
DEN = int (n, i = 0) [PRICE {i}], where
PRICE [i] = the price i bar (bars) back;
PRICE [0] = the current bar price;
PRICE [2] = the price 2 bars back.
从技术分析和交易的层面来看，该指标最主要的优势是有助于确定主要的支点并且没有滞后.
考察了多种价格过滤器的滞后和由各种不同系数导致的过激反应，为MetaTrader平台构建重心指标的想法出现了。SMA能够成为待选的过滤器之一，因为其所有的系数都有一样的值。结果表明SMA的重心正是过滤器的中心。
重心指标与随机震荡指标相似，唯一的不同是前者没有过买和过卖的区间。其主要信号来自于红蓝两条信号线。
信号线相交是该指标的主要信号：
由于产生较少的滞后，该指标可不依赖于其他过滤器单独使用。
另一个可由重心指标产生的信号是经典的背离信号:
