no bro... one big order at one price creates a buy or sell wall... this basically block the price from moving... this is actually the irresponsible action...

big orders are encouraged to split/spread it around... even ibkr has a tool for it... or do it otc to not disrupt the market...
I have no moral obligation to care about price movement. I bid at the price I want. Whether you want to sell to me at this price/yield is entirely your choice. We have different moral views haha. (My fiduciary duty is to "get the best execution price for my client (i.e. me)", not "generating liqudity and ensure market moves smoothly". That is the job of a market maker, which is why you have primary dealers for T-bills.)
Fair enough. But that is if you have the capital to do so. Retail investors won't have that luxury unless you go in at 10-20k SGD each time. It would be nice if I can split my bids at 100 SGD for 10 different bids, but minimum is 1k SGD, so I reserve that for the highest yield I believe to be reasonable.
Anyway, this is an auction, not continuous market making. In typical Sotheby-like artifacts auctions, I don't see bidders "split" bids like what you mention. The bidders just throw out any price they deem reasonable. MAS bills auctions differ from Sotheby-like auctions in that you can't inspect the order books before hand, nor can you see what other bidders are bidding in real-time. So there is no way you can "split" bids while ensuring no one bumps into you at the price range you bid. Not sure if your IBKR comparison is relevant to either case.
