I think this is pretty close.
// LISTING 1
//
plot candlestick price chart
Plot( Close, "Price", colorBlack, styleCandle
);
GraphXSpace = 1;
// define TAM chart period
//period = 25;
// users of AB Version 4.30 can use Param
period = Param( "TAM period",
25, 2, 100, 1 );
halfperiod = floor( period /2 );
// minor term
average
Arm = MA( Close, period );
Plot( Arm, "Minor term avg",
colorRed );
// calculate volatility
yom = 100 * ( C - Ref( Arm,
halfperiod ))/Ref( Arm, halfperiod );
avyom = MA( yom, 2 * period
);
varyom = MA( yom * yom, 2 * period ) - avyom * avyom;
som = Ref(
sqrt( varyom ), -halfperiod );
sigom = MA( som, period );
// plot
reference price grid
Plot( Arm * ( 1 + 0.01 * sigom ), "Ch+1",
colorLightGrey );
Plot( Arm * ( 1 - 0.01 * sigom ), "Ch-1", colorLightGrey
);
Plot( Arm * ( 1 + 0.02 * sigom ), "Ch+2", colorLightGrey );
Plot( Arm
* ( 1 - 0.02 * sigom ), "Ch-2", colorLightGrey );
Plot( Arm * ( 1 + 0.03 *
sigom ), "Ch+3", colorLightGrey );
Plot( Arm * ( 1 - 0.03 * sigom ),
"Ch-3", colorLightGrey
);
