Allow only selected strategies to be retested

Running the retester on EURUSD tick data runs all strategies on EURUSD data which is annoying when you don't want strategies for other markets tested on the market they were not initially made for. Instead, it would be helpful if only selected strategies were run on the market data I specify so that I can easily test one market at a time with as many strategies as I want without wiping the data from strategies of other markets on every retest.


The default method of running the test on all strategies in the databank should only occur if no strategies are selected. This will testing different risk models with specific strategies significantly easier as you can switch from one to the next and compare them in the same databank without having to constantly remove strategies from databank you do not want retested on the wrong data and then reloading them for comparison to the strategies you are testing.
