I made some improvements and fixed a few display issues. The major improment is the ability to show multiple time frames in a single chart. The original Stoch Thread newsgroup by Spudfyre (see link on first page) eventually began to discuss seeing multiple time frames on a chart. However, I wasn't that thrilled with their implementation of the idea.
Their indicator kept the same value across a higher timeframe which results in a stair step look which can be confusing to follow. Instead, the version I wrote will display the higher timeframes as a line chart. This way you can be on a 4H chart and see the stochastics for the 4H, the daily and the weekly at the same time. You can then really get a sense of what the overall trends for the time periods are doing.
There are 3 additional indicators with a suffix of "_multiTF". So attach those to the chart and they will use the original ones behind the scenes.
There is a new input for specifing Timeframe. In other MTF indicators I've seen, you have to put in the actual number of minutes per time period. Who knows how many minutes there are in a week off the top of their head? I sure don't. So instead, you just enter the chart code you'd like ie. M30 or D1 or W1. If you want it to automatically change when a chart changes just input "Chart". I think that's a lot more user friendly.
There's a new template file that shows an example of how the charts go together. Let me know if there's problems or anything else that you'd find useful.
