Algorithmic Trading
Using coded rules rather than discretion to generate signals, size positions and route orders, with the computer executing decisions.
What Algorithmic Trading means
Algorithmic trading means expressing a trading process as explicit rules that a program executes. The scope varies widely. At one end an execution algorithm simply works a large order into the market over time to reduce impact. At the other, a fully systematic strategy generates its own signals, sizes each position from an account-risk rule, submits the orders and manages exits without any human input. Retail implementations usually sit in a platform such as MetaTrader or cTrader; institutional ones connect directly through an API.
The genuine advantages are consistency and speed. A program does not skip a signal because the last three lost, does not widen a stop out of hope, and can watch dozens of instruments at once and act within milliseconds. It also produces a complete record, so results can be attributed to specific rules rather than to memory. That same rigidity is the weakness: a system keeps trading a market regime it was never designed for, and it will happily do so through a central bank surprise or an illiquid holiday session.
Practical failure modes are worth naming. Over-optimisation produces rules tuned to historical noise. Backtests that ignore spread, commission, slippage and swap overstate returns, sometimes enough to invert the result. Infrastructure introduces its own risks, including connectivity drops, duplicated orders after a reconnect and stale prices. Serious operators therefore add hard limits outside the strategy logic: maximum daily loss, maximum open exposure, and a manual kill switch that closes everything and disables new orders.
Worked example
A simple algorithm might buy EUR/USD when the 50-period moving average crosses above the 200-period average and risk 0.5 percent of equity per trade; over 200 trades a 3 pip round-trip cost that the backtest omitted would consume roughly 600 pips of gross profit.

Trade with a regulated broker
Understanding the terminology is the cheap part. The expensive part is choosing a counterparty whose execution, financing and withdrawal behaviour match what the marketing implies. Every broker below has been reviewed with a funded live account, and each review states which legal entity and which regulator applies to the account you would actually open.
