Better than what? Well, better than one indior that was used on some threads here onforexsoutheast.asiathat was not very well composed. There are probably others out there that are fine. There are also other'supertrend' indiors that are based on different formulas.

Supertrend Formula Copyright ©Unknown. Someone on the Internets.

Supertrend Formula:
UpperLevel=(High Low)/2 Multiplier*Atr(Stage );
LowerLevel=(High Low)/2-Multiplier*Atr(Stage );

Current Time-frame version
Do not repaint bars. Normal MT4 indior performance.
Ie. Have shifted. Draws the indior on the chart history without a performance penalty.
Multi Time-frame version
No external indior required. You might want to refresh the indior once MT4 begins up and downloads missing information as iCustom doesn't report such occasions. All pubs on the chart related to a greater bar that's open will continue to upgrade with the current standing of the until that bar closes, supertrend. You should not use the indior if you do not understand this.
Supertrend alarms:
Requires that xSuperTrend.ex4 is set up inorder to do the job. Optional popup and email alarms. Option to alert on bars or only when the current pubs closes.
