//| Behzad.mvr@gmail.com |
//+------------------------------------------------------------------+
// v1.2: History mode added. Set "historyMode" parameter to true then "double click" on any point in price chart to see Support and Resistance zones in that point.
// v1.3: Added parameter for sending notification to mobile phone when price entering S/R zones
// v1.4: Fixed Sup. & Res. labels in history mode.
// v1.5: Added Timeframe option to show S/R zones of a timeframe on other timeframes.
// v1.6: Optimization in finding the broken zones.
// v1.6: Reorganizing input parameters and deleting the unused codes.
// v1.6: Added prefix parameter, now you can add multiple instance of indicator to the chart by changing the prefix.
// v1.6: Fixed array out of range error when showing zones of a timeframe on other timeframes.
// v1.7: Buffers added for data window to show the strength of support and resistance zones and the type of zone if price is inside a zone.
