As has been mentioned on a number of different posts in response to your questions, the generator doesn't know 'where' it is in the generation process as it is not a sequential series of steps.
For clarification, the optimizer starts knowing how many steps are to be taken, eg:
Ind1 / Val1 / Start @ 10 / End 20 / Step 1
Ind1 / Val2 / Start @ 20 / End 30 / Step 2
Ind2 / Val1 / Start @ 10 / End 20 / Step 5
Ind2 / Val2 / Start @ 100 / End 1000 / Step 100
Ind2 / Val3 / Start @ 10 / End 20 / Step 1
Ind3 / Val1 / Start @ 10 / End 20 / Step 2
Before the optimizer starts, it knows that there are 108000 calculations to perform (10 x 6 x 3 x 10 x 10 x 6), so the code can just start at combination #1 and work forward until the end. At any time during the process, we could stop the process and restart later at the same point in the sequence.
The generator doesn't work in the same way (and not even in a close way).
The generator starts either starts with a totally new random strategy, or from the already loaded strategy (depending on the UI options), and works forward by adding/removing random indicators to the strategy throughout the process. It then combines this selection process with a rudimentary optimization of indicator parameters in an attempt to find a 'better' strategy.
The generator doesn't build a 'to do' list before starting.
The generator doesn't keep a list of every strategy that has been developed in the past (the Top 10 is the only data that is recorded).
There is nothing in the generator that would prevent the same calculation from being run multiple times.
So there is no way to know 'where' or 'how far' we are during the generator process as there is no defined starting or ending point, and no way to track the starting and/or ending point.
While it would be technically possible to build some form of analysis process that records every calculation made by the generator, and to have this presented in a graphical format, I'm not sure what value this would provide as there is no way to use the output to influence the calculation process inside the generator anyway.
