how a trade signal works
trade signals can use a variety of inputs from several disciplines typically technical analysis is a major component but fundamental analysis quantitative analysis and economics may also be inputs as well as sentiment measures and even signals from other trade signal systems the goal is to give investors and traders 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 asset class allocation such as shifting money among stocks bonds and gold 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 periodically 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 with great speed complex strategies could be rendered obsolete before testing is even finished example of a trade signaltrade signals tend to be associated with quick in and out trading however in reality some signals are less frequent and based on reversion and 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 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 dip if their signal is flashing good deal creating a trade signalthere 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 price to earnings ratio p e ratio buy when a certain technical formation breaks out to the upside and prices are above a certain moving average while interest rates are falling here are several of the more common inputs traders can combine them as they wish to meet whatever criteria they use to select trades
