I have a search which looks for high value stocks which have dropped below a moving average and now are moving above it. I want to be able to quickly see the percentage gain if the stock goes back to its previous high (resistance level). On each graph, the high price is clearly marked with a yellow triangle with an H inside it. I would like to be able to access that calculation of the high point in order to make a custom field that subtracted present price from previous high and used that as a divisor for the previous high.
