What do you mean make trials for withdraw? The last time i did a trade on binance was a while back and when I did this, it was me immediating trading a coin for another coin for whatever the current price was. I am not doing like those market or limit orders where i buy or sell when it hit a certain price.
Don't be too paranoid to try it dude, it just complicates yourself with time-consuming questions. You have been advised to try to execute your trade which means we understand that it will not risk anything to your account and assets. Actually you can finish your experiment in a few seconds instead of adding similar questions.
will it ask for confirmation or does it do it automatically?
No, if you get it you have to complain to support that it took you 5 secs to read and approve the confirmation. It must be removed
