Buying price for a stock that is recognised as Double Bottom by Pi Pattern Recognition

After a Double Bottom formation is complete, what should be the price at which the stock should be purchased? Assuming that volumes also should be considered important when buying that stock.Should the stock be bought around the resistance zone?

Thanks

If you are checking with the pattern recognition you can get it with next candle close price or by using Pivots as per your strategy and risk
