How to use a stop and limit order together?
You need to use one of each, so a single order wouldn't cover this:  The stop-loss order could be placed to handle triggering a sell market order if the stock trades at $95 or lower.  If you want, you could use a stop-limit order if you have an exit price in mind should the stock price drop to $95 though that requires setting a price for the stop to execute and then another price for the sell order to execute. The limit sell order could be placed to handle triggering a sell if the stock rises above $105. On the bright side, once either is done the other could be canceled as it isn't applicable anymore.
"if it opens below my limit order  What exactly are you trying to achieve here? If your limit order is for 100 and the stock opens ""below"" your limit order, say 99, then it is obviously going to buy it automatically.  also place a stop loss on the same order  Most brokers allow limit + stop loss order at the same time on same order.  What I conclude from your question is that you're with a broker that is using obscure technology. Get a better broker or maybe, retry phrasing your question correctly." "If you really believe in the particular stocks, then don't worry about their daily price.  Overall if the company is sound, and presumably paying a dividend, then you're in it for the long haul. Notwithstanding that, it is reasonable to look for a way out.  The two you describe are quite different in their specifics. Selling sounds like the simpler of the two, but the trigger event, and if it is automatic or ""manual"" matters.  If you are happy to put in a sell order at some time in the future, then just go ahead with that. Many brokers can place a STOP order, that will trigger on a certain price threshold being hit.  Do note, however, that by default this would place a market order, and depending on the price that breaks through, in the event of a flash crash, depending on how fast the brokers systems were, you could find yourself selling quite cheaply. A STOP LIMIT order will place a limit order at a triggered price.  This would limit your overall downside loss, but you might not sell at all if the market is really running away. Options are another reasonable way to deal with the situation, sort of like insurance.  In this case you would likely buy a PUT, which would give you the right, but not the obligation to sell the stock at the price the that was specified in the option.  In this case, no matter what, you are out the price of the option itself (hence my allusion to insurance), but if the event never happens then that was the price you paid to have that peace of mind. I cannot recommend a specific course of action, but hopefully that fleshed out the options you have." A stop-loss order becomes a market order when a trade has occurred at or below the trigger price you set when creating the order. This means that you could possibly end up selling some or all of your position at a price lower than your trigger price. For relatively illiquid securities your order may be split into transactions with several buyers at different prices and you could see a significant drop in price between the first part of the order and the last few shares. To mitigate this, brokers also offer a stop-limit order, where you set not only a trigger price, but also a minimum price that you are will to accept for your shares. This reduces the risk of selling at rock bottom prices, especially if you are selling a very large position. However, in the case of a flash crash where other sellers are driving the price below your limit, that part of your order may never execute and you could end up being stuck with a whole lot of shares that are worth less than both your stop loss trigger and limit price. For securities that are liquid and not very volatile, either option is a pretty safe way to cut your losses. For securities that are illiquid and/or very volatile a stop-limit order will prevent you from cashing out at bottom dollar and giving away a bargain to lurkers hanging out at the bottom of the market, but you may end up stuck with shares you don't want for longer than originally planned. It's up to you to decide which kind of risk you prefer. A stop-loss does not guarantee a sale at the given price; it just automatically triggers an unlimited sale as soon as the market reaches the limit. Depending on the development, your sale could be right at, slightly under, or deeply under the stop-loss limit you gave - it could even be it is never executed, if there are no further deals. The point is that each sell needs a partner that buys for that price, and if nobody is buying, no sale happens, no matter what you do (automated or manually) - your stop loss cannot 'force' a sale. Stop-loss works well for minor corrections in liquid shares; it becomes less useful the less liquid a share is, and it will not be helpfull for seldomly traded shares. I think if you are only trading stocks with average volume greater than 1M you should not have any trouble entering a 10,000 size trade. If you are you can try a couple of things: Change your order from a market order to a limit order, however this may potentially reduce the number of shares that are actually traded on that day, and you may miss out on some or all of your order. Limit your trading to more liquid stocks, say average daily volumes above 10M or 100M. Apart from that you might have to just put up with some extra slippage and incorporate it into your trading plan. That is you can reduce your R multiple to allow some slippage. If one wants to have a bound on the loss percentages that are acceptable, this is would be a way to enforce that. For example, suppose someone wants to have a 5% stop-loss but doesn't want this to be worse than 10% as if the stock goes down more than 10% then the sell shouldn't happen. Thus, if the stock opened in a gap down 15% one day, this triggers the stop-loss and would exit at too low of a price as the gap was quite high as I wonder how familiar are you with how much a stock's price could change that makes the prices not be as continuous as one would think. At least this would be my thinking on a volatile stock where one may want to try to limit losses if the stock does fall within a specific range. Your question is unanswerable as you haven't provided enough information. I.e. If those shares cost $1000 and you have $50000 ( or any number above $1000) of cash available in the account then you can't possibly free ride. I think your understanding of the free ride rule is incorrect. Basically what this rule is stating is that you have to have the cash when the trade is placed in order to settle the trade. Otherwise you are taking on margin (which you can't do in a cash account). So at order entry you have to have the cash to cover the purchase so it's able to be settled. If you do, no problem and you can sell that stock before trade settlement. There is no law that says you have to hold it past trade settlement. However, you cannot spend the same dollar more than once before it settles.  This site does a good job explaining this more throughly with examples: http://www.invest-faq.com/articles/trade-day-free-ride.html If you can afford the cost and risk of 100 shares of stock, then just sell a put option.  If you can only afford a few shares, you can still use the information the options market is trying to give you -- see below. A standing limit order to buy a stock is essentially a synthetic short put option position. [1]  So deciding on a stock limit order price is the same as valuing an option on that stock. Options (and standing limit orders) are hard to value, and the generally accepted math for doing so -- the Black-Scholes-Merton framework -- is also generally accepted to be wrong, because of black swans. So rather than calculate a stock buy limit price yourself, it's simpler to just sell a put at the put's own midpoint price, accepting the market's best estimate. Options market makers' whole job (and the purpose of the open market) is price discovery, so it's easier to let them fight it out over what price options should really be trading at. The result of that fight is valuable information -- use it. Sell a 1-month ATM put option every month until you get exercised, after which time you'll own 100 shares of stock, purchased at: This will typically give you a much better cost basis (several dollars better) versus buying the stock at spot, and it offloads the valuation math onto the options market.  Meanwhile you get to keep the cash from the options premiums as well. Disclaimer: Markets do make mistakes.  You will lose money when the stock drops more than the option market's own estimate. If you can't afford 100 shares, or for some reason still want to be in the business of creating synthetic options from pure stock limit orders, then you could maybe play around with setting your stock purchase bid price to (approximately): See your statistics book for how to set ndev -- 1 standard deviation gives you a 30% chance of a fill, 2 gives you a 5% chance, etc. Disclaimer: The above math probably has mistakes; do your own work.  It's somewhat invalid anyway, because stock prices don't follow a normal curve, so standard deviations don't really mean a whole lot.  This is where market makers earn their keep (or not). If you still want to create synthetic options using stock limit orders, you might be able to get the options market to do more of the math for you. Try setting your stock limit order bid equal to something like this: Where put_strike is the strike price of a put option for the equity you're trading.  Which option expiration and strike you use for put_strike depends on your desired time horizon and desired fill probability.  To get probability, you can look at the delta for a given option.  The relationship between option delta and equity limit order probability of fill is approximately: Disclaimer: There may be math errors here.  Again, do your own work. Also, while this method assumes option markets provide good estimates, see above disclaimer about the markets making mistakes.
