A simple swing range size indicator for 1H chart

We are looking for your help to build a very simple indicator that measures and displays the range of one point of swing to another. It works on the same principle as the zig zag indicator with the difference being it tells you how big the range between one swing point to another is. We're not entirely sure whether it is possible to make an accurate swing indicator as a swing is a subjective definition and any indicator that already does a similar thing produces results that heavily depended on the input parameters. If this is impossible to do (the accuracy of swing points on 1H chart), please let us know. In your bids, please explain to us the difficulty or the solution to find an accurate swing point. See picture attached for an example with hypothetical numbers. So in theory, if we can determine swing points accurately, we don't need any input parameters. The only input parameters we would like to have are the font, size, and color of the numbers, as well as the option of hiding or displaying the swing lines from one point to another (just like zig zag). This indicator must work on live data and it will repaint as new data comes in. Deliverable: 1 x custom-made indicator on mq4 format specifically made for 1H chart with generous comments on the code so we can make our own modifications. Thank you for your bids and cooperation. We're looking forward to work with you.
