Optimisation of strategy

[richa61416]

I currently have only 2 variables in my strategy. 1 for profit and 1 for Loss. HOwever when I run the optimisation with different ranges, it fails and tells me I have no parameters or some thing of the sort.

However the same strategy imported back to v6, I can run the optimisation with no problem.

If you don't mind could you strip the strategy down to its barebones and upload it? Is there any other information you can tell us about this behavior? Thanks.

Here is it stripped down.

Hi richa61416,

It would appear there are issues optimizing variables used on the Set() methods. Thanks for reporting. I will inform development.

Similar problem running strategy optimization

When I try to optimize a strategy with more than two parameters I get a message “There are no optimization results available, since the strategy has no parameters to optimize” even though the pre-run Optimize window shows the parameters and the same strategy and optimization parameters run fine in NT 6.0.

Hi raintree,

Thanks for reporting. Is this the same case as richa61416 reported or is this something different?

Since you have the following test...

if ( Close[5] > Close[0] )

You should first have the following test:

if (CurrentBar < 5) return;       // Make sure there are enough bars.

In a strategy it usually doesn't matter because BarsRequired is defined as 20 by default.

Good point.

This is a bug related to using some of the Draw... methods which occurs on backtest and workforward. It will fixed with next update. Thanks for reporting.
