BarUpDn time limited — Strategy by deimosaffair

trying to understand strategies, it appears that there is a lot of black magic in how a strat works behind the scenes.
anyway, it's hard to analyse what's all the data with one gazillion entries, and i wanted to know how we can manipulate/do stuff with a chart.

so, i needed to know how to "give" the script my values to work on. bundled two wants/needs into one, and created a script that only applies a strategy from the date given onwards.

how to use:
at the chart, go to the "format" little button, then the input tab, and there is all the date fields i created. fun to set it to the current date, then start going backwards and see all the little arrows filing up the chart :)
