strategy("[BACKTEST]Traders Dynamic Index Indicator Alert by JustUncleL", shorttitle="[BACKTEST]TDIALT")

// 
// author: JustUncleL
// date: 10-Oct-2019
// 
// Description:
//   This script is a "strategy" version of the "Traders Dynamic Index Indicator Alert v0.1 by JustUncleL"
//   made available for backtesting to help optimize settings.
//
//   This is a Trend following system utilising the Traders Dynamic Index (TDI),
//   Price Action Channel (PAC) and Heikin Ashi candles.
//   About while ago I came across the use of TDI in "E.A.S.Y. Method" that I found in
//   forexfactory forums: http://www.forexfactory.com/attachment.php?attachmentid=686629&d=1303831008
//   and I was able to set up a chart based on the specifications by using Kurbelklaus scripts.
//   However, I found that the alerts were being generated one or two bars too late,
//   so I was not successful using it with Binary Options. Later I found a variation of the
//   method in the forums which generates alerts a bit earlier, so this indicator is a
//   variation of that early detection version.
//   The indicator can optionally use Heikin  Ashi candles only for all it's calculations, 
//   I would recommend viewing the chart with normal Heikin Ashi candles, these
//   smooth out the trends and makes them more visible.
//
//   I found that this metod it works OK with currency pairs or commodities.
//   It also seems to work well with 5min+ timeframe charts, 
//   and for Binary Options I would suggest expiry of 2 to 6 candles.
//
//   ALERT GENERATION:
//   =================
//
//   The TDI (Traders Dynamic Index)
//   -------------------------------
//   Volatility Band VB(34), color: Blue, buffer: UpZone, DnZone
//   Relative Strength Index RSI(13)
//   RSI PRICE LINE (2), color: Green, buffer: mab
//   RSI TRADE SIGNAL LINE (7), color: Red, buffer: mbb
//   MARKET BASE LINE MID VB(34), color: Orange, buffer: mid
//
//   Indicator SignalLevels:
//   -----------------------
//   RSI_OversoldLevel : 22 (normally: 32)
//   RSI_OverboughtLevel : 78 (normally: 68)
//
//   Alert Conditions:
//   -----------------
//   Strong Buy (yellow): HIGH>PAC upper && BULL Candle && Candle High>PAC High && RSI>TRADE SIGNAL LINE && RSI>RSI_OversoldLevel && 
//                        && RSI<RSI_OverboughtLevel && TRADE SIGNAL LINE> MARKET BASE LINE
//   Medium Buy (aqua): HIGH>PAC upper && BULL Candle && Candle High>PAC High && RSI>TRADE SIGNAL LINE && RSI>RSI_OversoldLevel 
//                        && RSI<RSI_OverboughtLevel && RSI> MARKET BASE LINE && TRADE SIGNAL LINE< MARKET BASE LINE
//   Weak Buy (blue):   HIGH>PAC upper && BULL Candle && Candle High>PAC High && RSI>TRADE SIGNAL LINE && RSI>RSI_OversoldLevel
//                        && RSI<RSI_OverboughtLevel && TRADE SIGNAL LINE<MARKET BASE LINE && RSI< MARKET BASE LINE
//
//   Strong Sell (fuchsia): LOW<PAC lower && BEAR Candle && Candle Low>PAC Low && RSI<TRADE SIGNAL LINE && RSI>RSI_OversoldLevel 
//                        && RSI<RSI_OverboughtLevel && TRADE SIGNAL LINE< MARKET BASE LINE
//   Medium Sell (purple): LOW<PAC lower && BEAR Candle && Candle Low>PAC Low && RSI<TRADE SIGNAL LINE && RSI>RSI_OversoldLevel 
//                           && RSI<RSI_OverboughtLevel && RSI< MARKET BASE LINE && TRADE SIGNAL LINE> MARKET BASE LINE
//   Weak Sell (black): LOW<PAC lower && BEAR Candle && Candle Low>PAC Low && RSI<TRADE SIGNAL LINE && RSI>RSI_OversoldLevel 
//                        && RSI<RSI_OverboughtLevel && TRADE SIGNAL LINE> MARKET BASE LINE && RSI> MARKET BASE LINE
//
//   HIGH LEVEL FILTER (Overbought): RSI>=RSI_OverboughtLevel or MACD Histogram not green
//   LOW LEVEL FILTER (Oversold): RSI<=RSI_OversoldLevel or MACD Histogram not red
//
//   Hints on How to use:
//   --------------------
//   - When a Medium or Strong alert is generated and MACD histogram colour matches the direction
//     of the alert, then place trade in direction of alert candle and MACD.
//   - Use the multi-Hull MA's for trend direction confirmation.
//   - Best positions occur near the MACD(8,16,1) Histogram crossing the zero line.
//   - The optional coloured Dots along the bottom of the indicator represent the first alert 
//     of this type that was generated in this sequence.
//   - It is advisable to trade in the direction of the main trend as indicated the HULL MA red cloud:
//     if red cloud underneath PAC then BULLISH trend, if red cloud above PAC then BEARISH trend.
//   - Selecting the HeiKin Ashi candles does affect the MACD and MA caculations, so if you select
//     normal candles the result chart will change. Although the TDI calculations and alerts will stay the
//     same.
//   - When using the Heikin Ashi candles, a good buy entry is indicated by long top wick and no bottom wick
//     for bull (green) candles and good sell entry is indicated by long bottom wick and no top wick for
//     bear (red) candles.
//   - When the MACD histogram is flat and close to zero line,
//     this indicates a ranging market, do NOT trade when this occurs.
//   - When the PAC channel on the main chart is spread apart widely, this is an indication
//     of extreme volitity and choppy chart, do NOT try to trade during these periods.
//     A choppy chart is also indicated by Heikin Ashi candles with long wicks on both sides
//     of the candles.
//   - You can specify what strength level Alerts are generated (default 2):
//     Level (1) means only generate Strong Alerts only.
//     Level (2) means generate Strong and Medium Alerts.
//     Level (3) means generate Strong, Medium and Weak Alerts.
//
//   Modifications:
//   --------------
//     11-Oct-2019    
//          - Strategy Version for backtesting created.
//          - Converted to Pinescript V4
//
//     1.3  7-Aug-2017
//          - Modified Alertcondition code so that it only signals on the last completed alerted
//            candle. This should prevent some false alerts and multiple alerts being generated.
//            When setting alarms I suggest using Frequency "Once per bar (on condition)" to get
//            the earliest signal possible.
//          - Added optional alert long/short spikes that only occur on the first Long or Short//      Original code @author LazyBear for basic TDI indicator.

//            signals.
//     1.2  5-Aug-2017:
//          - Added new alerts for Buy and Sell (Long and Short) signals seperately.
//          - Upgraded to version 3 Pinescript.
//          - Added work around patch for opaque bar colouring issue.
//
//     1.1  - Modified code so when viewing Top chart with Heikin Ashi candles, calculations
//            are still based on standard candles, unless Heikin Ashi calculation option selected.
//
//     0.2  - Simplified MACD direction calculation to use just rising/falling.
//     0.1  - Oroginal Version
