strategy updating

[Marus]

I've notice that when updating several of my strategies that upon the time that I open a strategy within a chart to run it that the changes do not appear to update. A typical situation is when after running an optimizer and trying to set in the 'optimized' data to be the default, then saving. So the updates have not gone into effect, as well when going back to inspect the changes or re-apply them to the strategy, they updated data is entered correctly within the wizard.

Thank you,

Marus,

Sorry I did not quite follow you. If you change things in your code you need to load a new instance of your strategy to have all code changes fully propegated. If you are just trying to change some parameter values you need to set it to what you want and then right click > Set as Default. The next time you add this strategy it will use those defaults. Defaults you set do not change any instances of strategies already running. It affects things going forward after you have it set, not backwards.

Furthermore, setting defaults to optimizers sets the optimization range. There is no such range available for real-time running of your strategy. If you want defaults for real-time running of your strategy you would need to set those separately not from an optimization range.

Hi Josh,

In my past experience when I edit a strategy through the wizard and update the user defined inputs and save the changes, then go to a chart to load a new strategy (recently modified) the changes have appeared, the user defined inputs carry over to the new strategy being requested through the chart. In this case I am unable to see where the user defined inputs changes are updating to new strategey initiation/s. Thanks, hope this is a little clearer..

Changes to actual code will only propegate through the next time you add the strategy.
Changes to "defaults" from the optimizer do not carry over. Optimizer defaults are a range to run the values on. Running your strategy in real-time cannot use a range and as such this will not work. You need to set defaults to single values instead of an optimization range if you want it to carry over.

Yes, I understand what you said. I am changing a valuewithin the strategy from using a simple SMA crossover and I am unable to change the the assigned value to either SMA reload the strategy and have the new SMA values be inplace as they should be.. Thanks for trying anyway

Marus,

Pressing F5 to reload your strategy will not change the parameters. Only adding a new instance of the strategy will. Reloading will never change the parameters of a strategy as that would be unexpected behavior.

Hi Josh,

If I delete the strategy from all charts and from the control center strategies tab page and load in a new strategy the updates saved within strategy should be there, and it is or they are not.

Thank you for trying

Marus,

Unfortunately I am not following what you mean by your sentence because it is confusing. When you add a brand new instance of your strategy it will load any defaults you set. To set a default you actually have to right click in the properties grid and select "Set as Default for ______". This default can only be set for real-time use when you do not have a range selector available for your parameters. Meaning, setting defaults to optimizations or walk-forward optimizations will not carry over to real-time running of strategies or backtests. Only setting defaults from backtests or other real-time runs will you have the defaults carry over to another real-time run.

Hi Josh,

All I know is that what I am trying to expalin, poorly as it may be, is that in my case what does and did work in 6.5 (which I am using this morning) did not work in 7. I know we are both trying

Marus,

Perhaps if you gave me an exact sequence of listed steps from the very beginning I could see what you are doing. Please note that 6.5 did not have "Set Default for ________" behavior at all. This is brand new to 7.

If you could provide something like this, that would be perfect to get on the same page:
1. Open NT
2. Connect data provider
3. Open 1min chart of ES 06-10
4. Add strategy as enabled
... etc....

Thank you.

Hi Josh,

Open Nt7
Open workspace
connect to service provider
lots of time to load data as searching from 1/1/1800 to present
charts go back less than 20 days
right click on chart
strategies
scroll down to desired stragey and hit new
see that the default is not ideal for daily use example multiplier is 1.8
remove strategy
close
open strategy analyzer
scroll down to desired strategy
double click
editor opens
nest nest
user defined inputs; I see that it already reads 0.800 which is what I really want but today I'll change it to 3.4
next next next finish
right click on chart
strategies
scroll down to desired strategy
new
I observe that the multiplier is still 1.8

This should have updated (to my mind)
It has been ongoing for a couple of weeks and last week had major crash issues reloaded NT7

Please let me know the error of my ways

Thank you
