Hi I would like to know the trading platforms that accepts tokens like POStokens and ERC20 tokens aside from etherdelta thanks..
There are plenty of them, let me count the best known ones.
Bitrex is the high volume exchange. You can find many of the coins and erc20 tokens in bittrex.
Bitfinex is also a good known one, better to use for major altcoins rather than erc20 tokens.
Hitbtc contains lots of erc20 tokens, iou tokens and ICO project tokens. A trusted platform.
Liqui is another exchange for altcoins, but with low volume compared to other ones.
