I have been looking for an indicator for MT4 that alerts when prices closes / crosses above from below and also closes / crosses below from above Bollinger Bands.

Must be able to edit Bollinger Bands settings.

I have searched but to no avail, any one help ?

I am looking for a similar indicator on Bollinger bands
ie buy signal
1) Close cross lower BB 20 periods 2 Deviations &
2) RSI 14 periods cross or below 30 &
3) Stochastics 5,3,3 cros or below 20

Can someone please write this expert with sound alert for buy & sell signals
Thanks

Idea is to tweak bollinger bands so includes more ATR.
Bollinger relies on close only so this band is slightly different.

Is concept from 1993 Futures mag article.

TScode may help with idea. Shown below.
This plots but does not do the bands themselves.

Need an MQ4 that does these probability bands.

I have come across an ATRBands mq4 before , and there is the Keltner Bands too ,
The ATR bands when smoothed out are a close match to Keltner bands - so this may not be new, BUT think it is worth trying.




Variables : HighD(0), LowD(0), RangeD(0), HighW(0), LowW(0) , RangeW(0), AverageRangeD(0), AverageRangeW(0), DailyRange(0), WeeklyRange(0);

if DataCompression = 3 then
DailyRange = 12;
if DataCompression = 3 then
WeeklyRange = 52;


if DataCompression = 2 then
DailyRange = 5;
if DataCompression = 2 then
WeeklyRange = 21;

HighD = Highest(High,DailyRange);
LowD = Lowest(Low, DailyRange);
RangeD = (HighD - LowD);
AverageRangeD = Average(RangeD, DailyRange);


if close crosses below Plot1 then
alert ( "MARKET IS SHORT TERM OVERBROUGHT");

if close crosses above Plot2 then
alert ( "MARKET IS SHORT TERM OVERSOLD");

Plot1((Average(Close, DailyRange) + .5 * Average(RangeD, DailyRange)), "ST
OB");
Plot2((Average(Close, DailyRange) + .5 * Average(RangeD, DailyRange)), "ST
OS");

HighW = Highest(High,WeeklyRange);
LowW = Lowest(Low, WeeklyRange);
RangeW = (HighW - LowW);
AverageRangeW = Average(RangeW, WeeklyRange);

if close crosses below Plot3 then
alert ( "MARKET IS LONG TERM OVERBROUGHT");

if close crosses above Plot4 then
alert ( "MARKET IS LONG TERM OVERSOLD" );

Plot3((Average(Close, WeeklyRange) + .5 * Average(RangeD, WeeklyRange)), "LT
OB");
Plot4((Average(Close, WeeklyRange) + .5 * Average(RangeD, WeeklyRange)), "LT
OS");
