Don’t buy algos, says trader
@CARISTE warned against buying prebuilt trading algos, arguing markets adapt and can trap bought systems and showed a 24‑hour trade example. (x.com)
A trader posting as @CARISTE told followers not to buy prebuilt trading algorithms, saying any strategy sold widely can be learned and exploited by the market. (x.com) Algorithmic trading means using coded rules to place trades automatically when price, volume, or time conditions are met. Retail traders can now buy ready-made bots and signal systems on marketplaces that advertise “plug and play” strategies for stocks, foreign exchange, and contracts for difference. (ctrader.com) (prorealalgos.com) In the post referenced here, @CARISTE argued that once a strategy is packaged and sold, other traders can detect its behavior and trade against it. He paired that warning with a 24-hour trade example meant to show how quickly a setup can change once the market moves. (x.com) That argument lines up with a basic problem in automated trading: a backtest is a replay of old market data, not proof that the same pattern will keep paying in live markets. Quant research platforms and trading educators both warn that strategies can look strong in historical tests and then weaken out of sample, after costs, or after too many traders copy them. (quantconnect.com) (stefan-jansen.github.io) United States regulators frame the risk even more bluntly when bots are marketed with easy-profit claims. The Commodity Futures Trading Commission said in a customer advisory that fraudsters use artificial intelligence and automated-trading language to sell systems promising unrealistic or guaranteed returns, and that artificial intelligence cannot predict sudden market changes. (cftc.gov) The Securities and Exchange Commission, the Financial Industry Regulatory Authority, and the North American Securities Administrators Association issued a joint investor alert on January 25, 2024, warning that promoters use artificial-intelligence buzzwords to lure investors into scams. The agencies said investors should be wary of claims of high returns with little or no risk. (investor.gov) (finra.org) (nasaa.org) There is still a legitimate market for automation tools. Platforms such as QuantConnect and Backtrader sell infrastructure for research, backtesting, and live execution, while broker and platform stores list thousands of bots and indicators for sale. (quantconnect.com) (backtrader.com) (ctrader.com) Regulators do not ban algorithmic trading, but they do treat it as an area that needs controls, testing, and supervision. The Financial Industry Regulatory Authority says firms using algorithmic strategies are subject to Securities and Exchange Commission and Financial Industry Regulatory Authority rules, and the Commodity Futures Trading Commission’s proposed Regulation Automated Trading focused on pre-trade risk controls and testing standards for automated systems. (finra.org) (cftc.gov) @CARISTE’s warning lands in that gap between automation as a tool and automation as a product pitch. His point was that a bought algorithm is not a shortcut around market risk, and a strategy that everyone can buy may stop working when everyone can see it. (x.com)
