Buy limit order
A buy limit order buys only at your price or lower. It waits in the order book below the current price until sellers come down to it.
Price 100, buy limit at 97: if price falls to 97 you buy at 97, with no slippage; if it turns at 97.05, you buy nothing. Used to enter a long at a level, or as the take profit of a short. Placed above the price, it fills at once. The opposite is a sell limit order.
