Heikin-Ashi Technique and NMA aka NRTR Trading system

NMA(Nick Moving Average) alias NRTR(Nick Rypock Trailing Reverse Trading system) uses Heikin-Ashi Technique.

Heikin-Ashi is a type of candlestick chart that shares many characteristics with standard

candlestick charts, but differs because of the values used to create each bar. Instead of

using the open-high-low-close (OHLC) bars like standard candlestick charts, the Heikin-Ashi

technique uses a modified formula:

Close = (Open+High+Low+Close)/4
Open = [Open (previous bar) + Close (previous bar)]/2
High = Max (High,Open,Close)
Low = Min (Low,Open, Close)

The above formula can be achieved by the following afl code

HACLOSE=(O+H+L+C)/4;

HaOpen = AMA( Ref( HaClose,  -1 ),  0.5 );

HaHigh = Max( H,  Max( HaClose,  HaOpen ) );

HaLow = Min( L,  Min( HaClose,  HaOpen ) );
