No secondary market has developed for those tickers, because there simply is not anything to trade. There are only 2K shares held @ DTC for KTDR, RMLS and a whopping 20 for ONFA, so if those shareholders don't sell, there is nothing to buy, until someone else gets shares through clearing, and deposited, as the vast majority of the float would still be in certificate form, and not electronically tradable.
DTC only accepts deposits of securities from clearing firms, and clearing firms typically don't want to accept the liability, of clearing large blocks of shares, on any new trading ticker, especially those without adequate information, or filings, like those three.
I would be surprised to see a secondary market developing any time soon on those tickers, its possible a couple thousand shares could drop, but realistically those could still be 6 - 12 months away, if not longer, especially ONFA.
Those tickers would probably be best suited to go to the Chinese to use in RMs, which are typically a slower, and more long drawn process IMO.
