TD_I - indicator for MetaTrader 5

The TD_I indicator (Thomas DeMark Indicator) is a modified version of the standard DeMarker Indicator by Thomas R. DeMark.

The range of values ​​is from 0.0 to 100.0 instead of the standard 0.0-1.0. Additionally, a shift was introduced: instead of comparing current bar's High/Low with the previous bar's High/Low, this indicator uses current bar's High/Low and the High/Low price of the bar with the given shift, which allows to filter noises.

There are four input parameters:

• Period - calculation period;
• Shift - set to 1 by default, corresponds to DeMarker;
• Overbought - overbought level;
• Oversold - oversold level.

TD_I = 100.0 * HighAvg / (HighAvg + Low_Avg)

HighAvg = SMA(HighDiff, Period)
LowAvg = SMA(LowDiff, Period)
HighDiff = High - High[Shift]
LowDiff = Low[Shift] - Low
