Bollinger Band Squeeze (BBS) Indicator

A variation of an idea by nickm001 (Originally coded by eKam) that when Bollinger Bands (BB) fit inside the Keltner Channel (KC), a breakout is about to occur. It works on longer term charts, such as 15 minute to daily charts.

This code creates an indicator that plots the ratio of BB width to KC width. When BB and KC widths are the same, the ratio (BBS_Ind) is equal to one (1). When the BB width is less than the KC Width (i.e. BB fit inside KC), the BBS_Ind is less than one and a breakout is indicated.

An Alert Line is provided to indicate the level at which the trader considers that the "sqeeze is on" and a breakout is eminant.

Inside Ask Bid

This program prints the Inside Bid and Inside Ask on the chart.
You can choose to show the Bid/Ask as number or arrow.

Note: because most charting software are tick driven, i.e. it will only recal and update if there is a trade, therefore the bid/ask shown on the chart by this program is based on the bid/ask when last trade happened. If there is a change in bid/ask before the next trade happens, this new bid/ask will not be reflected on the chart. During thin market conditions, you might see a trade "appears" to push through the Bid/Ask boundary.


P.S. Program updated to work on the following charts: Hour, Minute, Second, Tick, Contract, Points(Range).

Anyone want to create a Slow Stoch where the line thickness of the K and D lines increases during overbought and oversold instead of plotting the overbought and oversold lines?

 

Just copy into new indicator window and verify. Width input determines width of line.

Code:

[color=blue]
[SameTickOpt = True];

inputs: 
	PriceH(  High),  
	PriceL(  Low), 
	PriceC(  Close), 
	StochLength( 7), 
	SmoothingLength1( 3), { used to slow FastK to FastD = SlowK }
	SmoothingLength2(  3), { used to slow FastD to SlowD }
	SmoothingType(  1), { pass in 1 for Original, 2 for Legacy }
	OverSold(  25), 
	OverBought(  75),
     Width(2);

 
 	variables:
	oFastK( 0 ), 
	oFastD( 0 ), 
	oSlowK( 0 ), 
	oSlowD( 0 ) ;

Value1 = Stochastic( PriceH, PriceL, PriceC, StochLength, SmoothingLength1, 
 SmoothingLength2, SmoothingType, oFastK, oFastD, oSlowK, oSlowD ) ;

Plot1( oSlowK, "SlowK" ) ;
Plot2( oSlowD, "SlowD") ;
Plot3( OverBought, "OverBot" ) ;
Plot4( OverSold, "OverSld" ) ;
Plot5(50,"ML");

If Plot1 > overbought then setplotwidth(1,width);
if plot1 < oversold then setplotwidth(1,width);



{ Alert criteria }
if CurrentBar > 2 then
	begin
	if oSlowK crosses over oSlowD and oSlowK < OverSold then { CB > 2 check used to
	 avoid spurious cross confirmation at CB = 2 (at CB = 1, MySlowK and MySlowD will
	 be the same) }
		Alert( "SlowK crossing over SlowD" )
	else if oSlowK crosses under oSlowD and oSlowK > OverBought then
		Alert( "SlowK crossing under SlowD" ) ;
	end ;
[/color]

 

Cool. Thanks.

BB BandWidth Indicator

BWI is a measure of an instrument's ability/tendency to trend.
It responses faster than ADX, and reset itself earlier.
When the BWI is low, there isn't any trend...
When it has a positive slope, there is a trend.
When a trend is lost, it can lead to a RTM movement.
