Trading : how to deal with crashes (small or big)
caveat: remember that complex derivatives can be very bad for your wealth (even if you FULLY understand them). You can buy out of the money put options that could minimize your losses (or even make you money)  in the event of a huge crash. Put options are good in that you dont have to worry about not getting filled, or not knowing what price you might get filled with a stop-loss order, however, put options cost money and their value decays over time. It's just like buying insurance, you always have to pay up for it.
I understand the question, I think. The tough thing is that trades over the next brief time are random, or appear so. So, just as when a stock is $10.00 bid / $10.05 ask, if you place an order below the ask, a tick down in price may get you a fill, or if the next trades are flat to higher, you might see the close at $10.50, and no fill as it never went down to your limit.  This process is no different for options than for stocks.  When I want to trade options, I make sure the strike has decent volume, and enter a market order. Edit - I reworded a bit to clarify. The Black–Scholes is a model, not a rigid equation. Say I discover an option that's underpriced, but it trades under right until it expires. It's not like there's a reversion to the mean that will occur. There are some very sophisticated traders who use these tools to trade in some very high volumes, for them, it may produce results. For the small trader you need to know why you want to buy a stock or its option and not worry about the last $0.25 of its price. In my experience thanks to algorithmic trading the variation of the spread and the range of trading straight after a major data release will be as random as possible, since we live in an age that if some pattern existed at these times HFT firms would take out any opportunity within nanoseconds. Remember that some firms write algorithms to predict other algorithms, and it is at times like those that this strategy would be most effective. With regards to my own trading experience I have seen orders fill almost €400 per contract outside of the quoted range, but this is only in the most volatile market conditions. Generally speaking, event investing around numbers like these are only for top wall street firms that can use co-location servers and get a ping time to the exchange of less than 5ms. Also, after a data release the market can surge/plummet in either direction, only to recover almost instantly and take out any stops that were in its path. So generally, I would say that slippage is extremely unpredictable in these cases( because it is an advantage to HFT firms to make it so ) and stop-loss orders will only provide limited protection. There is stop-limit orders( which allow you to specify a price limit that is acceptable ) on some markets and as far as I know InteractiveBrokers provide a guaranteed stop-loss fill( For a price of course ) that could be worth looking at, personally I dont use IB.  I hope this answer provides some helpful information, and generally speaking, super-short term investing is for algorithms. You will lose out on your spread, you always pay a spread. Also, if you are looking at a strategy for using stop losses, try taking into account the support lines if you are going long. So, if the stock is on an upward trend but is dropping back from profit taking, your best best is to take a position closest to the next support line. You place your stop just below the support. this will give you the best chance of a winning position as most technical analysts will have looking towards the support as a buy back area. Obviously, in a bear market the opposite is true.  If you have taken your position and the market move past the first resistance line, then bring your stop to just below that line as once resistance is broken, it then becomes support. You then have a profitable position with profit locked in. Leave the position to break the next resistance and repeat. Cash would be the better alternative assuming both stocks take a major hit in ALL categories AND the Fed raise rates at the same time for some reason. Money market funds that may have relatively low yields at the moment would likely be one of the few securities not to be repriced downward as interest rates rising would decrease bond values which could be another crash as I could somewhat question how broad of a crash are you talking here. There are more than a few different market segments so that while some parts may get hit really hard in a crash, would you really want to claim everything goes down? Blackrock's graphic shows in 2008 how bonds did the best and only it and cash had positive returns in that year but there is something to be said for how big is a crash: 20%, 50%, 90%? What is essential is that company you are selling is transparent enough. Because it will provide additional liquidity to market. When I decide to sell, I drop all volume once at a time. Liquidation price will be somewhat worse then usual. But being out of position will save you nerves for future thinking where to step in again. Cold head is best you can afford in such scenario. In very large crashes, there could be large liquidity holes. But if you are on upper side of sigmoid, you will be profiting from selling before that holes appear. Problem is, nobody could predict if market is on upper-fall, mid-fall or down-fall at any time. The short answer is if you own a representative index of global bonds (say AGG) and global stocks (say ACWI) the bonds will generally only suffer minimally in even the medium large market crashes you describe.  However, there are some caveats. Not all bonds will tend to react the same way.  Bonds that are considered higher-yield (say BBB rated and below) tend to drop significantly in stock market crashes though not as much as stock markets themselves.  Emerging market bonds can drop even more as weaker foreign currencies can drop in global crashes as well. Also, if a local market crash is caused by rampant inflation as in the US during the 70s-80s, bonds can crash at the same time as markets.  There hasn't been a global crash caused by inflation after countries left the gold standard, but that doesn't mean it can't happen. Still, I don't mean to scare you away from adding bond exposure to a stock portfolio as bonds tend to have low correlations with stocks and significant returns.  Just be aware that these correlations can change over time (sometimes quickly) and depend on which stocks/bonds you invest in. "Between 1 and 2 G is actually pretty decent for a High School Student.  Your best bet in my opinion is to wait the next (small) stock market crash, and then invest in an index fund. A fund that tracks the SP500 or the Russel 2000 would be a good choice. By stock market crash, I'm talking about a 20% to 30% drop from the highest point. The stock market is at an all time high, but nobody knows if it's going to keep going.  I would avoid penny stocks, at least until you can read their annual report and understand most of what they're claiming, especially the cash flow statement. From the few that I've looked at, penny stock companies just keep issuing stock to raise money for their money loosing operations.  I'd also avoid individual stocks for now. You can setup a practice account somewhere online, and try trading. Your classmates probably brag about how much they've made, but they won't tell you how much they lost.  You are not misusing your money by ""not doing anything with it"". Your classmates are gambling with it, they might as well go to a casino.  Echoing what others have said, investing in yourself is your best option at this point. Try to get into the best school that you can. Anything that gives you an edge over other people in terms of experience or education is good. So try to get some leadership and team experience. , and some online classes in a field that interests you." Short the Pound and other English financial items.  Because the English economy is tied to the EU, it will be hit as well.  You might prefer this over Euro denominated investments, since it's not exactly clear who your counterpart is if the Euro really crashes hard.  Meaning suppose you have a short position Euro's versus dollars, but the clearing house is taken down by the crash. Buy low, sell high. I think a lot of people apply that advice wrongly. Instead of using this as advice about when to buy and when to sell, you should use it as advice about when not to buy and when not to sell. Don't buy when P/Es cannot support the current stock price. Don't sell when stocks have already fallen due to a market panic. Don't follow the herd or you will get trampled when they reverse direction in a panic.  If you are smart enough to sell ahead of the panics, more power to you, but you should be using more than a 52-week high on a graph to make that decision. While trading in stochastic I've understood, one needs reference (SMA/EMA/Bolinger Band and even RSI) to verify trade prior entering it. Stochastic is nothing to do with price or volume it is about speed. Adjusting K% has ability to turn you from Day trader to -> swing trader to -> long term investor. So you adjust your k% according to chart time-frame. Stochastic setup for 1 min, 5 min ,15, 30, 60 min, daily, weekly, monthly, quarterly, half yearly and yearly are all different. If you try hopping from one time-frame to another just because it is below oversold or above overbought region with same K%, you may get confused. Worst you may not square-off your loss making trade. And rather not use excel; charts gives better visual for oscillators. "After learning about things that happened in the ""flash crash"" I always use limit orders. In an extremely rare instance if you place a market order when there is a some glitch, for example some large trader adds a zero at the end of their volume, you could get an awful price.  If I want to buy at the market price, I just set the limit about 1% above the market price. If I want to sell, I set the limit 1% below the market price. I should point out that your trade is not executed at the limit price. If your limit price on a buy order is higher than the lowest offer, you still get filled at the lowest offer. If before your order is submitted someone fills all offers up to your limit price, you will get your limit price. If someone, perhaps by accident, fills all orders up to twice your limit price, you won't end up making the purchase. I have executed many purchases this way and never been filled at my limit price." A lot of people here talk about shorting stocks, buying options, and messing around with leveraged ETFs. While these are excellent tools, that offer novel opportunities for the sophisticated investor, Don't mess around with these until you have been in the game for a few years. Even if you can make money consistently right out of the gate, don't do it. Why? Making money isn't your challenge, NOT LOSING money is your challenge. It's hard to measure the scope of the risk you are assuming with these strategies, much less manage it when things head south. So even if you've gotten lucky enough to have figured  out how to make money, you surely haven't learned out how to hold on to it. I am certain that every beginner still hasn't figured out how to comprehend risk and manage losing positions. It's one of those things you only figure out after dealing with it. Stocks (with little to no margin) are a great place to learn how to lose because your risk of losing everything is drastically lower than with the aforementioned tools of the sophisticated investor. Despite what others may say you can make out really well just trading stocks.  That being said, one of my favorite beginner strategies is buying stocks that dip for reasons that don't fundamentally affect the company's ability to make money in the mid term (2 quarters).  Wallstreet loves these plays because it shakes out amateur investors (release bad news, push the stock down shorting it or selling your position, amateurs sell, which you buy at a discount to the 'fair price'.) A good example is Netflix back in 2007. There was a lawsuit because netflix was throttling movie deliveries to high traffic consumers. The stock dropped a good chunk overnight.  A more recent example is petrobras after their huge bond sale and subsequent corruption scandal. A lot of people questioned Petrobras' long-term ability to maintain sufficient liquidity to pay back the loans, but the cashflow and long term projections are more than solid. A year later the stock was pushed further down because a lot of amateur Brazilians invest in Petrobras and they sold while the stock was artificially depressed due to a string of corruption scandals and poor, though temporary, economic conditions. One of my favorite plays back in 2008-2011 was First Solar on the run-up to earnings calls. Analysts would always come out of these meetings downgrading the stock and the forums were full of pikers and pumpers claiming heavy put positions. The stock would go down considerably, but would always pop around earnings. I've made huge returns on this move. Those were the good ole days. Start off just googling financial news and blogs and look for lawsuits and/or scandals. Manufacturing defects or recalls. Starting looking for companies that react predictably to certain events. Plot those events on your chart. If you don't know how to back-test events, learn it.  Google Finance had a tool for that back in the day that was rudimentary but helpful for those starting out. Eventually though, moreso than learning any particular strategy, you should learn these three skills: 1) Tooling: to gather, manipulate, and visualize data on your own.  These days automated trading also seems to be ever more important, even for the small fish. 2) Analytical Thinking learn to spot patterns of the three types:  event based (lawsuits, arbitrage, earnings etc), technical (emas, price action, sup/res), or business-oriented (accounting, strategy, marketing). Don't just listen to what someone else says you should do at any particular moment, critical thinking is essential. 3) Emotions and Attitude: learn how to comprehend risk and manage your trigger finger. Your emotions are like a blade that you must sharpen every day if you want to stay in the game. Disclaimer: I stopped using this strategy in 2011, and moved to a pure technical trading regime. I've been out totally out of the game since 2015. It was a forex account (foreign exchange trading).  At that time forex brokers were not regulated or required to be regulated so it was like the wild west.  It was indeed a learning experience and thankfully I was diversified so the hit hurt but did not ruin me. Ok, so disregarding passivity, could you help me through a simplified example?   Say I only had two assets, SPY and TLT, with a respective weight of 35 and 65% and I want want to leverage this to 4x.  Additionally, say daily return covar is:  * B/B .004% * B/S -.004% * S/S .02%   Now, if I read correctly, I should buy ATM calls xxx days in the future.  Which may look like: Ticker, S, K, Option Price, Delta, Lambda  * TLT  $126.04  $126.00  $4.35  0.50  14.5 * SPY  $134.91  $134.00  $6.26  0.55  11.8  ^ This example is pretty close but some assets are far off.   I feel like I'm on the wrong track so I'll stop here.    I just want to lever up my risk-parity. Margin rates are too high and I'm docked by Reg-T. I would refrain from commenting on market timing strategy, but please don't park extra AUD cash in IB.  Park cash in your local bank high interest savings, and get a Margin account at IB.  When you want to pull the trigger, use margin loan to buy stocks immediately, then transfer cash from local bank to IB afterwards.
