Hi. I have a question about limit orders. Say I am looking to buy a stock, future or forex, and I create a limit order at price + 0.001. meaning I want price + 0.001 or better (lower). If someone places a market order (or a limit at price) which reaches the exchange / bank slightly after me, will my limit order take the cheaper liquidity at 'price' if it is still there or will the exchange bump the market order ahead of mine, giving it the cheap liquidity and filling me at price + 0.001, my accepted limit? is this different on different markets?
