Name Of Indicator :BB squeeze (for MT4)
What It Should Do :
1) Identify BB squeeze (see parameter setting below)  at beginning AND at end by using standard deviation (SD) values derived from Bands indicator in MT4 platform. To avoid several alerts on the same bar especially in long TF, please make the decision to send alert on closed bar
2) Send email alert, pop ups
3) Mark the line where Begin & End with diff color than Bands indicator

Required Parameters:
1)The SD filter Default =(4.0%) Can be changed to 2 decimal
2) Send email alert True/False
3) Send pop ups True/False 

Others :
1) Text box contains the SD value when a mouse is hover on it
2) Email message can be the format “ (BB squeeze [BEGIN/END] at [CURRENCY PAIR], [TIME FRAME]. SD value is [ FILTER VALUE%]
3) I would like the indicator requires little processing powers as possible as I would running several indicators on multiple charts thru VPS. Therefore parameters is up for discussion.

Example : Using 4% as SD filter
Bar 1 SD =4.33% (No alert)
Bar 2 SD =3.91% (Alert – Beginning of squeeze)
Bar 3 SD =3.43% (No alert – previous bar is already in filter range)
Bar 4 SD =4.45% (Alert – End of squeeze)
