Instead of trading like you're in a bazaar in middle east, focus on doing your research. Know your worth, and how to substantiate your worth during an interview.
Tell the numbers openly when asked, bodily and proudly, and have it confirmed that falls into their budget, and back up your worth with an adequate interview.
Can you imagine doing five rounds only to discover your ask would have never be met, that's madness, how can people suggest that?
Absolutely unprofessional, wastes everyone time, and put all the chances into a single, high stake rounds of wage roulette. And who has the most to lose there?
Especially in countries with limited PTO, just tell that number, and filter out interviews that would have lead to inadequate offers.
Instead of taking the problem with random adhesiveness, just put all that effort upfront and go in the meeting with a number that is well researched both in terms of matching or beating the market and in terms of allowing you to earn your living.
You can always tune the ask down if you're not getting enough interviews, or up if your getting too many. If you get a job too easy, pass and look for a better one, use the job market signal about your performances against itself.
Your ask and the demand will put passing interview on a Gaussian curve. From there is just a repetition game. Ask too much and you'll need infinite time to get a job, but knowing the variance you can establish an ask that matches your time horizon.
