I tested it for a while and it looked awesome!
Just little minor suggestions
-The stop message, please take it away : D (I lnow you said it will be removed)
-I personally would like it to search like 20 times same search with the same parameters before moving to next one, but this is just my personal preference because it feels so slow when it changes parameters after each search.
-This one is really minor, but requires much coding and l'm not even sure can it be done with autohotkey. After the first seach, the bot checks if you have some same parameters in the next search that you had in the first one. This enables the bot to "skip" deleting one parameter and then selecting it again and writing the amount. Would make the bot faster
