InBarMtfAlert
The sliding multi-taymfreymovy indicator narrowing volatility ID / NR.
1. External variables:
extern int TF = 15; // Number of candles emulate senior possibly custom TF
extern int NR = 4; // Number of candles older FFs, among which sought inner candle
extern bool UseAlert = false; // Use the alert.
2. The appearance of the signal (ARROW) indicates the ID / NR state (according to L. Raschke). In this case (default parameters) - this means that the last TF = 15 formed bars of the current timeframe have the price range the narrowest of TF * (NR = 1), TF * (NR = 2), TF * (NR = 3) And TF * (NR = 4) for the last TF * NR = 15 * 4 = 60 bars. In addition, the range of the last 15 bars is internal to the range of the previous 15 bars. Zero bar is not taken into account.
3. The indicator lines (LINE) - are similar to the Donchian channel line and show the corresponding volatility. There is an average line.
4. The lines of the indicator (SECTION) connect the moments of signal occurrence (ARROW) on the history.
