Are your interested in High-Frequency Trading (HFT) or Algorithmic Trading? As /u/RogerL mentioned, the infrastructure speed and access time are critical factors in succeeding with HFT. It is a costly endeavor outside the reach of majority of traders. Algorithmic Trading can be done by anyone who can research and identify inefficiencies and implement strategies to exploit such inefficiencies. Typical such opportunities are short-term so you have to constantly develop new ones and refine old ones and know when the old ones are no longer working. > I have a trading bot for that & it used to work well with some market volatility, but it's a waste when the market's sideways. Rising tide raises all boats. Even a monkey throwing darts on a list of stocks can do well in rising markets. No one strategy works across all phases of market.
