Buy condition - consider 3 candles -2, -1 and 0. 0 is current candle, -1 previous, -2 2nd previous candle
1. Candle -1 should have made a newlow from previous candle low (-2) 
2. Candle -1 closes above Open
3. Candle -1 High less than previous high (-2)
4. Sound Alert should appear with Entry, SL, TPs when current candle breaks high of Candle -1, Entry price = first tick price > high (-1) (Option to turn on/off this alert after candle close or during active candle (0)) and alert should appear only once.
5. Buy Arrow should be placed on Candle -1 once the condition is met and must not repaint.
6. Fibonacci Extension levels to be plotted based on the High (-1) and low (-1) with SL as Low -1 and TP Values (TP1 - 1.618, TP2 - 2.0, TP3 2.618, TP4 - 3.236, TP5 - 4.236)
7. There may be minor enhancements requested based on outcome but not a major change though

Note : I have an indicator that already does the job for -2 and -1 candles and if needed can be shared.
