What Is a Trade Signal?
A trade signal is a trigger for action, either to buy or sell a security or other asset, generated by analysis. That analysis can be human generated using technical indicators, or it can be generated using mathematical 澳洲幸运5开奖号码历史查询:algorithms based on market action, possibly in combination with ꧋other market factors such as economic indicators.
Key Takeaways
- Trading signals are triggers to buy or sell a security based on a pre-determined set of criteria.
- They can also be used to reconstitute a portfolio and shift sector allocations or take new positions.
- Traders can create trading signals using a variety of criteria, from simple ones, such as earnings reports and volume surge, to more complex signals that are derived using existing signals.
How a Trade Signal Works
Trade signals can use a variety of inputs from several disciplines. Typically, 澳洲幸运5开奖号码历史查询:technical analysis is a major component, but fundamental analysis, 澳洲幸运5开奖号码历史查询:quantitative analysis, and ec🉐onomics may also be inputs, as well as sentiment measures and even signals from other trade signal systems. The goal is to give investors and trade🐲rs a mechanical method, devoid of emotion, to buy or sell a security or other asset.
Aside from simple buy and sell triggers, trade signals can also be used to modify a portfolio by determining when it might be a good time to buy more of one particular sector, such as technology, and lighten up on another, such as consumer staples. Bond traders, meanwhile, could have signals for adjusting the duration of their portfolios by selling one maturity and buying a different maturity. Finally, it can also help with 澳洲幸运5开奖号码历史查询:asset class allocation, such as shifting money among stocks,ꦺ bonds, and gol🅰d.
There is no limit to how complex a trade signal can be. However, traders tend to keep things simple by using only a handful of inputs. For practical purposes, it is far easier to manage a simple signal generator and periodicalౠly test it to see what components need adjusting or replacing.
Too many inputs would introduce complexity requiring more time than a trader has to offer. And since markets change over time, often wiꦗth great speed, complex strategies could be rendered obsolete before testing is even finished.
Example of a Trade Signal
Trade signals tend to be associated with quick in and out trading. However, in reality, some signals are less frequent and based on reversion and 澳洲幸运5开奖号码历史查询:dip-buying in equities.
Great trading signals of this sort would be to look for periods where price action doesn't line up with the underlying 澳洲幸运5开奖号码历史查询:fundamentals. An example would be if the market is selling off due to fear headlines, but the fundamental data indicates good health. Traders may decide to buy the di💧p if their signal is flashing "good deal."
Creating a Trade Signal
There are endless possibilities when coming up with a trade signal, but traders tend to just want to automate their thinking. An example might be, "for a stock with lower than a certain 澳洲幸运5开奖号码历史查询:price-to-earnings ratio (P/E ratio), buy when a certain technical formation breaks out to the upside, and prices are above a certain 澳洲幸运5开奖号码历史查询:moving average while interest rates are falling."
Here a💝re several of the more common inputs. Traders can combine them as they wish to meet whatever criteria they use to select trades.
- 澳洲幸运5开奖号码历史查询:Technical pattern breakout or break down. These can include 澳洲幸运5开奖号码历史查询:triangles, rectangles, head-and-shoulders, and trendlines.
- 澳洲幸运5开奖号码历史查询:Moving average cross. Most investors watch 50- and 200-day moving averages but there are many others in common use. The input could be when trading activity crosses above or below the average. Or it could be when two averages cross each other.
- Volume surge. Unusually high volume is often a precursor to a new move in the market. In the futures markets, 澳洲幸运5开奖号码历史查询:open interest can also be used.
- 澳洲幸运5开奖号码历史查询:Interest rates. Changes in rates can often suggest changes in stock and commodity markets.
- 澳洲幸运5开奖号码历史查询:Volatility. There are many ways to measure volatility and, as with other indicators, extreme highs or lows in volatility can trigger market changes.
- Cycles. Markets of all types tend to ebb and flow over time, even if they are in a steady trend or in a non-trending condition. One of the more widely known cycles is the seasonal cycle for stocks—澳洲幸运5开奖号码历史查询:sell in May and go away—which could help determine if a strategy is operating in the strong or weak half of the year.
- 澳洲幸运5开奖号码历史查询:Sentiment extremes. Used as a 澳洲幸运5开奖号码历史查询:contrarian indicator, excessive bullishness according to surveys or actual trading activity can suggest market tops. Conversely, excessive bearishness can lead to market bottoms.
- 澳洲幸运5开奖号码历史查询:Valuation. An excessively high valuation compared to market, sector, or stock-specific measures can lead to sell signals.
