Ok, look. You've mentioned the fact that you lack some information about the trades that you didn't enter but planned to, to make proper decisions on trading strategy. Untill you get this information, you'll keep yourself stuck in doubts of what to do with your next trades' ideas (to enter the trade with market orders, leave it as is, or plan limit orders more generously). Numbers are your only friends here. The solution is obvious. You need to get the numbers for each particular outcome and see the overall results for each of three options.
You see, now that you know that you need these numbers, half problem is solved. You only need to work on getting these numbers.
I think that it can be a good idea to create a row in Excel of Google Sheet each time you see the possibility on the market (pattern or situation that makes you think of placing the order). Next in the end of the day you can go through each of these rows and enter the values of profit/loss for each of the approaches: aggressive enry, loose entry, normal entry.
Of course this is just a basic idea and it requires polishing. However, this is how you can do that. This advise is very precise.
Yes, it will take time. You'll feel reluctant working with these spreadsheets. However, if you don't put yourself in a situation when you need to spend 12 hours in raw manually entering all these values at once for 100+ raws, you'll be fine. The result will not come overnight, but in a month or two you'll have enough stats to make conclusions about the strategy. These conclusions will have some scientific ground! And it won't be tht painful if you do some work every day.
