Tom DeMark连续热图策略
Author: 雨幕（youquant）, Date: 2022-06-06 11:30:10Tags: TD
该指示器使用Tom DeMark从1到13的TD顺序计数。 数字9和13通常识别一个耗尽的趋势，并标记一个趋势反转。 重要数字显示为标签（7-13），其中9和13均突出显示为“多”或“空”。
除数字外，价格蜡烛还根据顺序上色。 看涨的颜色从亮黄色（TD 1=趋势开始）到深红色（TD 13=趋势耗尽） 熊市的颜色从亮蓝色（TD 1=趋势开始）到深蓝色（TD 13=趋势耗尽）
DeMark建议仅用于短期价格反转，但如图所示，它也适用于LUNA 1D图表。 也可以很好地与Heikin Ashi蜡烛配合使用。
例如，将其与“Tom DeMark压力比”结合使用，以找到顶部和底部。 您可以更改时间范围，禁用标签/条形图颜色，并根据自己的喜好自定义颜色。

////////////////////////////////////////// Tom DeMark heatmap © by Indicator-Jones /////////////////////////////////////////
//
// This indicator uses Tom DeMark’s TD Sequential counting from 1 to 13.
// Number 9 and 13 usually identify an exhausted trend and mark trend reversal.
// The important numbers get displayed as labels (7-13), where 9 and 13 are both highlighted as "Long" or "Short".
// Besides the numbers the price candles are colored based upon the sequence.
// Bullish colors are starting from bright yellow (TD 1 = start of trend) to dark red (TD 13 = trend exhausted)
// Bearish colors are starting from bright blue (TD 1 = start of trend) to dark blue (TD 13 = trend exhausted)
//
// DeMark recommends to be used for short term price reversals only but as you can see in the chart, it also works for LUNA 1D chart.
// Also works very well with Heikin Ashi candles.
// Use it in combination with for example the "Tom DeMark Pressure Ratio" to find tops and bottoms.
// You can change the timeframes, disable lables/barcolor and customise colors to your liking.
//
// If you have any idea on how to optimise the code, please feel free to share :)
//
// Inspired by "Stochastic Heat Map" from @Violent
