// Title: "Bollinger Band and ADX Retrace Alert v0.1 by JustUncleL".
// Author: JustUncleL
// Date:   22-Jul-2016
// Version: 0.1
//
// * Description *
//   Brief: This strategy follows variation of a well known Bollinger band + ADX reversal 
//          strategy. Includes warning alert conditions. Can be used 1min to 15min charts.
//
//
//   Full:  Bollinger is standard calculated from SMA (20,2).
//          The strategy is we wait for a candle that breaks and closes outside
//          the Bollinger Bands and then filter on ADX and market direction: if
//          the ADX(6,20) is below level 25 and optional market direction filter applied.
//          Market direction (as indicated by 180/60 EMAs) needs to in the opposite
//          direction  to breaking candle. We place the binary trade on the 
//          following candle in opposite direction of breaking candle.
//          Martingale can be used, but only at most 2 levels, otherwise count trade as 
//          a loss, I use 10,25,60 or 10,30,90 Martingales.
//
//          Breakout identified by shapes:
//          The red or green hightlighted diamonds will normally pre-warn alert
//          for PUT/CALL to place trade on the NEXT candle after alert confirmed
//          on close of break candle.
//          If using 1min charts then place 60sec or 120sec binary trade.
//
//          Trade wisely, 1min candle trading can be fun, but also risky. Try
//          in Demo first. Only perform 5 trades a session. This strategy does not 
//          genrate many alerts, particularly with market direction filter, but they
//          are normally pretty good.

@UtterOnceOlufayo, Yes, but you have to enable it when add the Alert to your alarms in "Manage Alerts" panel in Tradingview.
