I assume that MAINLY the reason you wish to set a GTC high price on your shares here is to PREVENT them from being borrowed and used for short selling. I may be wrong but am of the opinion that it can and still will be done anyway. GME reportedly had 140% of their shares shorted as an example as to why I am stating that. ILLEGAL as that might be the SEC seems uncapable of doing its regulatory job. The only other way to assure your shares cannot be used for shorting is to take delivery on them in cert form and have them stored at home , but that method makes trading them inconvenient. CASH accounts as I understand them cannot be loaned out , but I find that hard to believe that in practice it is adhered to currently.
Currently with all the people (investors) that believe the market is rigid against them am surprised that no one has created an online trading brokerage that 100% does not allow shares held there by its clients to be loaned out and no shorting. Am thinking they would get a lot of business from retail investors.
