Srategy inputs - optimization
Posted: 08 Feb 2008
I have noted several issues that make the signal inputs and optimizations a bit less intuitive and have added steps.
1. Optimizations are not done through the input window.
2. Optimization results do not produce signals.
Details.
When you begin the process to "build" a chart with signals, you add the strategy to the chart and when you close it, the signals appear. Assuming you want to optimize some of those parameters you open optimization and input the variable ranges you want to optimize and then begin the process. Upon the optimization completion, the optimization report opens without any result selected. Therefore there are no signals on the chart and should you reopen the optimization, the optimization results are not saved in the optimization window. Even if you select and optimization output there are no signals presented. Therefore should you choose to run an optimization of other parameters you must manually change the values in each input to result otherwise it will repeat the optimization again (example to follow). Additionally should you select one of the optimization outputs from the report. Before you can see signals, you must close everything. If you want to visually check other optimization outputs, you must re-open the optimization report and then you can select the various optimizations and it will change the signals.
Example
Strategy has 3 inputs, Upon opening you will see the following
Signal name Input name Start Value End value Step
Happy Days------#1------------1--------------1----------1
Happy Days------#2------------1--------------1----------1
Happy Days------#3------------1--------------1----------1
It would be quicker for the user if variable inputs could be saved to a user default so that upon opening (assuming I set this strategy to these defaults previously) it would look like....
Signal name Input name Start Value End value Step Run(check-box)
Happy Days------#1------------1--------------21---------1------------X
Happy Days------#2------------1--------------21---------1
Happy Days------#3------------1--------------21---------1
Upon the optimization completion, assuming I ran just #1 above I would see (upon reopening)...even though test 11 was selected by me.
Signal name Input name Start Value End value Step
Happy Days------#1------------1--------------21---------1
Happy Days------#2------------1---------------1---------1
Happy Days------#3------------1---------------1---------1
Upon completion and assuming I wanted the output result of test 11, I need to enter it to run just #2.
Signal name Input name Start Value End value Step
Happy Days------#1------------11-------------11---------1
Happy Days------#2------------1---------------21--------1
Happy Days------#3------------1---------------1---------1
IT would be better if upon completion of the optimization and selection of the test from the optimization report it looked like.
Signal name Input name Start Value End value Step Run(check-box)
Happy Days------#1------------11-------------11---------1
Happy Days------#2------------1---------------21---------1-----------X
Happy Days------#3------------1---------------21---------1
Hope this was clear,
Thanks
