What is
algorithmic trading?
Decisions come from rules written in advance, not from emotion — and rules can be tested.
What is algorithmic trading?
It means turning a strategy into explicit rules: which conditions open a position, which conditions close it, how much risk is taken. Once the rules are written, the decision is driven by data rather than interpretation.
So the foundation of algorithmic trading is not prediction — it is definition. A vague instinct cannot be tested. A written rule can.
Who uses it?
Institutional funds
To manage large volumes in a rule-driven, auditable way.
Professional traders
To measure their own strategies and turn them into systems.
Individual investors
To separate decisions from emotion and stop living in front of a screen.
Why it matters
At the center of everything:
backtesting
Until you have seen how a set of rules behaved on historical data, nothing is known about those rules. A backtest is not a promise — it is a measurement.

Why TrendArcher fits this work
What you won't find elsewhere
No look-ahead
Every row is computed only from what was known at that moment. The next candle's information never leaks into the decision.
Pre-computed indicators
Indicator values are calculated and stored in advance, so a backtest reads them instead of recomputing 142 values every minute.
Live and historical, cross-validated
The live pipeline and the historical one are held to the same output and compared value by value.
Undefined is not zero
When a value cannot be computed it stays empty. It is never quietly written as zero.
