RE: XXX: Split Adjustments.

Welcome back! I hate it when I loss a password, so I usually use one of two different passwords on websites. If it ain't one of them, its the other!

Split Adjustments: For the NDX SI and Osc, it's a "don't care". It only looks to see if the price was higher or lower then the previous close. This will cause one data point to be incorrect and should not mess up thing too bad, only about 1% for one day.

However, for the MACD breadth it will cause a problem. For me, it is a easy adjustment with AmiBroker. It finds where there has been a split and adjusts the historical prices. For you, since you are dealing with the raw data, you could do one of two things:

1. Take all historical prices before the day of the split and divide or multiply the value to adjust for the split. I think this one will be the easiest.

2. Put in a multiplier or divider with a date and symbol and all future price will be adjusted. This may be more difficult, or easier if you can put it into your code with ease. You are probably a better programmer than me.

Let me know how you do it.

Yes, I still feel that the hourly chart do gauge short term trends, but since the top on 1/11, the short term trends have gotten much faster and with trying to trade EOD, it was getting to whippy for me, so I went to cash and am waiting for the daily breadth (same chart as below, but based on daily data) to give me a direction. I think with any indicator, knowing when to use it and how to use it is sometimes more art than science! :)

I will try and post my daily charts later on today, maybe before the close. It does appear that we are bouncing off that downtrend line again, being confirmed by a some weakning breadth.

Thanks for your charts and thoughts!
