Best way to beat/end a ddos attack is to shut down the whole server/ restart the modem and all should be good because whatever ip stresser their using will end and stop sending huge amounts of traffic.

Lol

Alright let's break this down
insulting my competence. Sorry if this was ambiguous, but that's not what I meant there. I said "I could tell you were experienced at - something - (if not GE workings, nor politeness) due to the quite rare level of competence". Specifically, your level of competence is quite rare, i.e. you are refreshingly competent, I bet you are skilled at something. But yeah that was badly worded from me on mobile rip.
Saying I'm not being polite while... You cannot use such language and expect politeness back, you let the cat out of the bag and now we're both rude for it lol.
You think that pricing data can't be used well, or in a timely manner, and that's all I really needed to know. That's right! You certainly can use the price and margin for flipping, but when it comes to wanting to buy something right now, no amount of price data will help you buy it faster or cheaper.
Accuse me of being unfamiliar/questioning my experience. If you think that putting in an offer at +20% means you can expect to pay +20% every time, this is unfamiliar. That's just not how the GE works
There's not many good bots that do it, because they're not familiar with markets or how well the APIs can be used, but it's very possible. I agree, and have done the same IRL algorithmically with cryptocurrency to a reasonable degree of success. However, it involves trades that (1) may not go through and (2) tie up lots of resources and time. Whilst this is useful for a flipping bot, these techniques and their associated pricing data do not help here, where the problem is to buy an item as fast as possible.
I don't think you give a shit at this point. Depends on some balance of the demand/effort/impact on a per-feature basis.
The function works 'well enough' and that's that for you. Yup, making such a change (including some speculative advance-buying technique and stoppage-correction) would take a lot of effort and make a low impact, due to the way the GE works above. You are the only person who has ever suggested it, so there is low demand, although it's fair to assume that most people probably don't realise this is a possibility.
Forgive me for being so daring as to suggest that there's room for improvements. Np, feel free to suggest more! Just don't be throwing around words like incompetent, foundationally-flawed, terribly designed, etc, unless you are willing to defend them and potentially have them thrown back.
