Using a random coin as an example, if the last price is 1.08999944 how can i chose either a buy or sell price that will be a valid 'maker' price ? Can i just bump the price by one Satoshi i.e. 1.08999945 and put a buy.. making it a maker order and take advantage of lower fee ?
Looking at various coins order books there seems to be a lot of open orders so to make a valid maker order do i need to first query the order book for open orders and then find a gap at a price i like and then place the order ?
I understand the maker is
... maker fee if the trade order is not matched immediately against an order already on the order book, which is adding liquidity.
I'm just not sure how you know in advance of placing the order that it will not match an open order ?
