Charmeta, Do you want to specify the "given bar" or do you want the calculation performed for every bar? If you want to compare the value of the Stoch() on every bar with the value of the Stoch() in the 250 preceeding bars, as far as I can figure, you cannot in the native MS Formula Language? By my reckoning, this is one of those (many) times when the loop function that cannot be done in MS is sorely needed. If you were only looking for say 20 or so periods there is a way to synthesise a loop, it isn't pretty but it works. The synthetic solution is out of the question for 250 bars. Loops can be easily done using external codes. If you want to specify the bar on which to start the computation be a date or some other event, this can be achieved. If you want to compare the Stoch() in the last 250 bars on the chart, this too is achievable. Provide a little more detail if you can, and we shall see what we can collectively achieve. wabbit :D

If you want a variable Stoch indicator, this can be found in the free Forum.dll from the downloads section of the forum. If you are looking for self-levelling indicators, then I can send you some stuff I developed some time a go, in the native MS formula language, or look here http://forum.equis.com/viewtopic.php?t=3157 If you want a custom external solution to count the bar, then you are going to have hire a code cutter to program it for you. I can do this for you, Jose can do it and there are others too. wabbit :D
