Is there a function that tells how long a condition has existed?

[crmcwi]

Guys, I want to be able to know how long a moving average has been flat. Is there a Function that can look back like CountIf(), but with an unlimited scope?

I want to use this information to then determine how the market oscillates above and below its mean. I want to be able to describe the range so I can trade it while it lasts and then trade the breakout.

Does anyone have any suggestions please?

crmcwi, I think you can work with LRO for this to check since how many bars back condition x returned true - http://www.ninjatrader-support.com/H...urenceLRO.html

LRO not quite right

Thanks Bertrand, I appreciate it.

The LRO, however, requires a lookback period. I need a function that will return the number of bars for which a condition is continuously true.

For example, let's say that 78 minutes ago, a SMA went flat. I would like a function that can tell me that. In CQG, for example, there's a WHEN() function that will tell you the last time a condition was true or false. You can ask, "when was the SMA not flat", for example and it will return 79 in our case.

If such a function does not exist in NJ Script, have you come across anything that was custom coded? Please advise, thank you, Craig.

Craig, unfortunately I'm not aware of one not needing a lookback period input - but you could custom code this yourself, just save the current bar number to a variable when your condition for the flat MA triggers and then take the difference from the CurrentBar to this variable for the value you seek.

yep, cool. thank you. when I do, I would like to post it for the community. Is there a vetting process or coding standard?

We would appreciate a post in the sharing section of our forums when this finalized - http://www.ninjatrader-support2.com/...splay.php?f=37

As for a coding standard, please take a look at the system indicators and reference samples for how the code is structured and formatted.
