说明：  德马克指标，划线分析趋势指标，属于指标文件，没有源码德马克指标是由美国投资专家Tom Demark先生创建，久经历史考验。这一指标较少的为一般的投资者所知，但在一些专业的交易员和机构中却口口相传。 和一般技术指标不同，这一指标在确认趋势反转反面有很大帮助
(Demark indicators, trend indicators of underlined analysis, belong to the index document. No source Demark indicators were created by American investment expert Mr. Tom Demark, who has experienced the test of history for a long time. This indicator is less known to ordinary investors, but it is passed on by word of mouth among some professional traders and institutions. Unlike general technical indicators, this indicator is very helpful in identifying the reverse trend.)
