Indicator needed for Nanningbob strategy

The programming forum has been great with help on Nanningbob's strategies. I need help with an indicator that would help with backtesting of his latest 6x6 strategy. His EA enters at the cross of two moving averages-6 linear weighted applied to median price with a shift if 0 and when it crosses a 6 LW med. price shift1. My request is an indicator that would look back at a cross and tell you at what price exactly did the cross happen. You can look back at a cross and see that it crossed sometime within a candle but you have to guess about what price the cross occurred within the candle. Can someone take the guess work out for me? The chart below shows a cross sometime within the 4HR candle. What was the exact price at the cross? That's what I'm after. Thank you very much.

Usually this is not a difficult request - I do something very similar with other indicators. However, your MAs use the median price, which uses 2 price points - high AND low. This causes a problem - I'll spare you the technical details. The best we could do in your situation is tell you the median price of the candle when the MAs crossed. However, for backtesting purposes, this would not be helpful since, at any given time, the median price of a candle can certainly differ from the actual price (current price) of a candle.

Now, if your MAs used 1 price point (close, open, high, or low), then the exact cross price can be calculated.

Thanks ZZ. I guess if an indicator isn't possible(with the median price) I can run it through the strategy tester to see were cross was.
