Let's say at the time you happen to be looking at TSLA, it is $425.00 bid, $425.35 ask. The last trade was at $425.00, with recent prior trades in the range of $425.00 to $425.17. size is currently 50x50. You could enter a limit order to sell at $425.34, to see if your offer is immediately joined by another seller. You could then continue to reduce your offer until you get to $425.18, or until the seller stops joining your offer. Let's say the seller joins you to $425.18, but you get filled (short) at $425.17, after you enter a limit sell order at that price. Now you could put an order to buy at $425.01. If no other buyer joins you there, you can leave it there to see if more aggressive selling later comes in. If a buyer did join you at $425.17, then you have a decision to make, probably using additional inputs. If buyers later come in instead, first by joining your bid, then bettering it, you can make a decision to either increase your bid or see if the previous seller is willing to accept $425.18, for a small loss if you believe the stock has turned. It would be an especially bad sign if prices now started to exceed $425.18. If prices started to trade at $425.35 or higher, your seller definately bolted, at least for the time being. From here, I let you draw your own conclusions have to manage a trade like this for various scenarios.
