Perhaps if you share what you're tyring to implement I can help you come up with a solution.

Sure, I have a filter with realcode condition in a 5 minutes timeframe running every 5 mins.
The values I am interested to get from this 5 mins timeframe are mainly prices (low,high,...). I want to be able, while in the 5 minutes timeframe, to access information from a higher timeframe (15 mins, 60mins, daily, for example). The values I want to read from higher timeframes are in general indicators stochastics, MAs, and others.
Things I want to do: (in fact this is what I am doing, but using registries...)
1. I am in the 5 minutes timeframe and I can read the high and low prices, it's easy to determine the price is moving down. If I can get the MA20 value from a daily timeframe, then I can implement the following rule:
- if the price crosses down the daily MA20, don't do anything (let's say I am not interested in a breakdown), but if it crosses up (after 1,2, 10mins), then alert me, because there is a good chance this is bounce back from daily MA20.
2. Catch discrepancies between trends in different time frames and convergence of indicator values from different time frames.
3. Calculate upside/downside potential. You know the way the market turns, usually a whole sector goes down, then it  turns. When the reversal occurs, SF5 calculates the potential  for gain for each stock, based on distance from local position to major resistance support levels (from higher time frames) and gives  me the possiblity to choose the one with maximum potential. If a stock has 3% upside from current position to MA20 daily, compared to another one from the same group with a 5%, it's easy for me to make a choice.
And I can keep going till tomorrow...

What I want to have is access to data (indicator values) from any timeframe. Most of this can be done now with the filters & sort columns but cannot implement the kind of logic and fine tunning I want. My mehod is also optimized, do not have to run a filter every 5 mins to get data from a 60 mins timeframe.

This is what I am doing now:
1. I execute one time only (in the morning) a realcode condition in a filter with daily timeframe for my watchlist.
This condition reads indicator values from the daily time frame for each symbol and writes the information in the registries (I have a tree structure).
This means that I have now in registries the daily indicator values for each symbol.
2. I execute another realcode condition in a filter with a 60mins time frame for my watchlist (runs every 60mins).
This condition reads indicator values from the 60mins time frame for each symbol and writes the information in the registries. The information is updated every 60 mins.
This means that I have now in registries another set of values for each symbol from a 60 mins timeframe
3. I execute another realcode condition in a filter with a 5 mins time frame for my watchlist (runs every 5 mins).
This condition reads the information stored in the registries by the first 2 conditions. The whole logic is in this condition, and makes use of data read from registries (in fact from different time frames). This gives me a high control over what & when I want to trigger. I use debug log as output, because I can centralize everything in one place and it's easy to compare/decide which stock I should go with.

Thank you

Your goal is more of a global memory share accross charts or between charts and watchlist columns.

As an aside and not advancing Stockfinder's capabilities, it occurs to me you could load your 5 minute data into the registers as well and have a seperate application manage the alert announcements. This would permit a more dynamic announcement than the debug.log.

1.  Locking not required.  Each variable has a realtime value that persists until it is changed, or the application exits, period.

Flash 99. Would an easier solution be the ability to access any symbol/timeframe from RealCode?

You just don't understand Flash99. If we are not concerned about threading and locking issues, then you will get bad data in your global memory and ask us why it's wrong. 

Registries are disabled going forward.

The next build will also add the ability to get price data for any symbol from any time frame from within your RealCode.

I'm looking into how feesable it is to move the shared hash object into a global domain.

You can put any collection you want in the key/value pairs.

I barely understand about 50% of what you guys talkign about, so enough to be dangerous.

has there been any new developments since February '10 ? Is the chapter on global variables in the 2nd edition realcode manual still valid?
with my little realcode experience, and if I interpret things correctly, I think this could help me in certain circumstances.
For example I have some indicators, that draw trendlines, and price projections. I'd like to create some conditions, but I don't see another way to do this by eiher duplicating the code, or somehow be able to share variables between the indicator and a condition. 

Kuff, or any of the experienced coders, could you post some simple examples, and explain in laymen terms how it works? Once I understand the "do's" and "don'ts", I think I'll be able to implement it in my layouts.
