How to start high-frequency trading
Starting HFT involves a systematic approach to ensure success in the fast-paced and competitive market. Here is a step-by-step algorithm to guide you:
Learn as much as you can. Begin by thoroughly studying Forex, stock and crypto markets, trading strategies, and the principles of high-frequency trading. Familiarize yourself with market mechanics, order types, and the impact of high-frequency strategies on execution.
HFT strategy is the key. Create a well-defined and tested high-frequency trading strategy. It should be based on statistical analysis, technical indicators, or market patterns, designed to capitalize on rapid price movements.
