How does one determine the width of a candlestick bar?
Very common question. There is no any rule of thumb. This solely depends on your trading strategy. I will share my own experience. My day starts with the daily chart, if I have a signal, either I open my position or I check 30 minute chart to make sure that it won't go too much against my trade. and I open my position. If I am waiting for the signal the minimum timeframe is 4 hours for me. I use 30 minutes to find the best time to enter the market. So, this is totally something special for my trading strategy, that is why those things can change based on the different strategies. I also check weekly and monthly charts to confirm trend. I have been busy with forex since 2007 and I am a verified investor on etoro At the end, I never use 1,5,15,60 minute charts as they are against my strategy. You could theoretically use any time period unit, but 1 minute and 30 minute  seem to be the most common and useful.  Especially for active traders.  This also has the added advantage of giving you useful insight into the trade volumes throughout the day; assuming that is also included on the chart.  I think most include that as a bar chart across the bottom. Here is a great example for crude oil on dailyfx:  https://www.dailyfx.com/crude-oil Notice that the chart has time options at the top left which include 1 minute, 30 minutes, 1 hour, and 1 day. There's no rule of thumb but the purpose of candlesticks of any kind (fixed, volume weighted etc.) is to display the intra-period price action. So if you'd fit 3 years worth of 1 minute bars on a chart, candlesticks become useless and you might as well use a line chart.
This strategy is called trading the 'Golden Cross' if the 50 day SMA moves above the 200 day, or the 'Death Cross' when the 50 day SMA moves below the 200 day SMA. Long-term indicators carry more weight than shorter-term indicators, and this cross, in a positive direction signals a change in momentum of the stock. You will not catch the very bottom using this method, but there is a better chance that you will catch a move near the beginning of a longer-term trend. Golden Cross Information - Zacks "The size terminology for lumber is based on the rough cut dimensions from the mill, not the actual size of the board at Home Depot. There's post finishing done to 2x4's, etc from the big box stores.  It's been that way for 50 years.  If a couple of hipsters got their feelings hurt because they didn't know what they were doing, tell them to watch a youtube video about lumber before screwing up a home improvement project.  They wouldn't have the slightest idea what to do with an actual rough cut 1x6 anyway.  They'd get home with it, and if by some miracle they managed to plane it, they'd realize they're left with a 3/4""x5 3/4"" board,  just like you get from Home Depot.  Grow up, pansies." A shorter term MA would be used for short term changes in price whilst a long term MA would be used for longer term movements in price.  A 200 day SMA is widely used to determine the trend of the stock, simply a cross above the 200 day SMA would mean the stock may be entering an uptrend and a cross below that the price may be entering a downtrend. If the price is continuosly going above and below in a short period of time it is usually range trading. Then there are EMAs (Expodential Moving Averages) and WMAs (weighted moving averages) which give more emphasis to the latest price data than the earlier price data in the period chosen compared to a SMA. MAs can be used in many different ways, too many to list all here. The best way to learn about them is to read some TA books and articles about them, then choose a couple of strategies where you can use them in combination with a couple of other indicators that are complimentary with each other. Someone referred to the bend as a living hinge, I've heard it referred to as a kerf-bend.  My office has a laser cutter and might be interested in putting it to use.  What kind of volume are you looking for?  If low-volume, PM me. "Hello! I am working on a project where I am trying to determine the profit made by a vendor if they hold our funds for 5 days in order to collect the interest on those funds during that period before paying a third party.

"&gt; 41x92x1820mm  1.6""x3.6""x71.7"", which is more or less the same as in the US.  2""x4"" is the rough cut board before drying and finishing. Anyone who regularly works with wood knows this. It's been the industry standard for decades." http://dailyfinance.com Enter a stock ticker, then click on the Chain link to the left. Then, click on the option tickers to see their charts. EDIT: the site has changed, and there are no more option charts. So why are option charts so tough to find? Options are derivatives of the stock. Option prices are defined by a formula. The inputs are stock pricxe, strike, days to expiration, dividend, risk-free interest rate, and volatility. Volatility is the only thing that cannot be easily looked up. With a Black-Scholes calculator, and some reasonable volatility selections, it's possible to make your own fairly accurate option chart. I don't think it's very enlightening, though. The interesting things are: the stock price movement (as always), and the nature of option pricing behavior in general (understanding how the formula represents crowd behavior). "You cannot determine this solely by the ticker length. However, there are some conventions that may help steer you there. Nasdaq has 2-4 base letters BATS has 4 base letters NYSE equity securities have 1-4 base letters. NYSE Mkt (formerly Amex) have 1-4 base letters. NYSE Arca has 4 base letters OTC has 4 base letters. Security types other than equities may have additional letters added, and each exchange (and data vendors) have different conventions for how this is handled. So if you see ""T"" for a US-listed security it would be only be either NASDAQ, NYSE or NYSE Mkt. If you see ""ANET"" then you cannot tell which exchange it is listed on.  (In this case, ANET Arista Networks is actually a NYSE stock). For some non-equity security types, such as hybrids, and debt instruments, some exchanges add ""P"" to the end for ""preferreds"" (Nasdaq and OTC) and NYSE/NYSE Mkt have a variety of methods (including not adding anything) to the ticker.  Examples include NYSE:TFG, NYSEMkt:IPB, Nasdaaq: AGNCP, Nasdaq:OXLCN.  It all becomes rather confusing given the changes in conventions over the years. Essentially, you require data that provides you with ticker, listing location and security type. The exchanges allocate security tickers in conjunction with the SEC so there are no overlaps.  eg. The same ticker cannot represent two different securities. However, tickers can be re-used.  For example, the ticker AB has been used by the following companies:" Candlesticks and TA are a relic of pre-computer trading, period. Market makers use sophisticated algorithms not for trading, but manipulations. Why would I go to amazon at 9pm at night to buy 2-4 to fix a broken box spring? Or go to amazon to purchase a handful of the right size screw which I sit and measure with an extra screw I bring? (My last two trips) "Each candlestick in a candlestick chart represents the open, close, high and low for a period of time. If you are looking at a daily chart it represents the open price, close price, high price and low price for that day. If you are looking at an hourly chart, then a single candlestick represents the open, close, high and low prices for an hour. If looking at a weekly chart, then a single candlestick will represent the opening price on Monday morning, the closing price on Friday afternoon, and the highest and lowest price for that week. The diagram below represents the two main types of candle sticks.  When the price closes higher than they open for the period of the candlestick it is called a bullish candle and the main body is usually represented in green. When the price closes lower than they open for the period of the candlestick it is called a bearish candle and the main body is usually represented in red. In a bullish candle with a large real body and small shadows or wicks, where prices open near the low of the period and close near the top of the period, it represents a very bullish period (especially if volume is high). An example of this situation could be when good news is released to the market and most market participants want to buy the shares driving prices higher during the period. An example of a bullish candle with a small real body and a large upper shadow or wick could be when market participants start buying early during the period, then some negative news comes out or prices reach a major resistance level, then prices drop from their highs but still close higher than the open. The large upper shadow represents some indecision in prices moving higher. In a bearish candle with a large real body and small shadows or wicks, where prices open near the high of the period and close near the low of the period, it represents a very bearish period (especially if volume is high). An example of this situation could be when bad news is released to the market and most market participants want to sell the shares driving prices lower during the period. An example of a bearish candle with a small real body and a large lower shadow or wick could be when market participants start selling early during the period, then some positive news comes out or prices reach a major support level, then prices move up from their lows but still close lower than the open. The large lower shadow represents some indecision in prices moving lower. These are just some examples of what can be derived from looking at candlestick charts. There are plenty more and too much to include in this answer.  Another type of candle is the Doji, represented in the diagram below.  The Doji Candle represents indecision in the market. Prices open then move up to the high of the period then start falling past the open before reversing again and closing either at the open or very close to the open. The market participants can't decide whether the price should move up or down, so prices end up closing very close to where they opened. A doji Candle close to a market high or low could represent a turning point in the short term trend and could mean that over the next period or two prices could reverse and go in the opposite direction. There are many more definitions for candlestick charts, and I would recommend an introductory book on candlestick charting, like one from the ""Dummies"" series. The main things to keep in mind as a beginner it that a strong bullish candle with small shadows and large real body could represent further price movement upwards, a strong bearish candle with small shadows and large real body could represent further movement downwards, and any candle with large shadows could represent indecision and a reversal from the direction of the large shadow." John Person has a pattern called the High Close Doji that is probably the most reliable signal in the world of candle patterns. I would check out Candle Stick and Pivot Point Trade Triggers.

"Your questions In the world of technical analysis, is candlestick charting an effective trading tool in timing the markets? It depends on how you define effective. But as a standalone and systematic strategy, it tends not to be profitable. See for example Market Timing with Candlestick Technical Analysis: Using robust statistical techniques, we find that candlestick trading rules are not profitable when applied to DJIA component stocks over 1/1/1992 – 31/12/2002 period. Neither bullish or bearish candlestick single lines or patterns provide market timing signals that are any better than what would be expected by chance. Basing ones trading decisions solely on these techniques does not seem sensible but we cannot rule out the possibility that they compliment some other market timing techniques. There are many other papers that come to the same conclusion. If used correctly, how accurate can they be in picking turning points in the market? Technical analysts generally fall into two camps: (i) those that argue that TA can't be fully automated and that interpretation is part of the game; (ii) those that use TA as part of a systematic investment model (automatically executed by a machine) but generally use a combination of indicators to build a working model. Both groups would argue (for different reasons) that the conclusions of the paper I quoted above should be disregarded and that TA can be applied profitably with the proper framework. Psychological biases It is very easy to get impressed by technical analysis because we all suffer from ""confirmation bias"" whereby we tend to acknowledge things that confirm our beliefs more than those that contradict them. When looking at a chart, it is very easy to see all the occurences when a certain pattern worked and ""miss"" the occurences when it did not work (and not missing those is much harder than it sounds).
