interactive strategy chart

[NinjaTrader_JoshP]

ATI user,

I still do not quite understand what you are trying to do exactly. If you want a switch can't you just program it into the strategy itself? I don't think you need an indicator.

[ATI user]

I think your boolseries may do the trick...working on it now.

The switch I need is a manual switch and must be outside the strategy because when I change a parameter in the strategy, the chart refreshes...and I lose all plots/data prior to that point in time.

will advise...thanks

no...looks like I need to write to/read from a file

[ATI user]

ok...I give up

you can not write/read to/from the same file at the same time...so that will not work.

So the question remains: How do I change a parameter setting in a strategy without using the Parameter Settings dialog for the strategy?

[NinjaTrader_JoshP]

You cannot change parameters on the fly.

For the file reading/writing, just close the file and reopen it after each process. I don't see why you would need to read and write simultaneously. You can read then write or write then read.

[ATI user]

Problem with that is the strategy needs to be constantly reading and can not be disturbed or the chart will refresh...or...can the file be closed within the code?...if so, how please

I could have the strategy check somehow to see if the file is open before it tries to access (to avoid the error message). Is this possible?

sw.Close();

for a StreamWriter named sw. You are working on very hairy grounds. You will probably get a ton of errors on historical data closing/reopening. No way to guarantee that the indicator has closed the file before the strategy tries to open it.

interactive alert

further to my posts 1 and 3 in this thread, NT has pop-up alerts which have the OK option to close the pop-up.

could these not be made interactive..i.e. change OK option to Yes, No and Close/OK...so that some action could be initiated?....without refreshing the chart of course

main question = why can we not (in a new version) change parameters in a strategy on the fly without having the strategy recalculate the entire chart with the new setting ....thereby erasing all prior plots etc??

Thank you for the suggestion ATI user. I have forwarded it to development.
