Backtest

Replays historical bars through a strategy with explicit execution assumptions. Simulated fills are not guaranteed to have been executable in the real market.

1. Data

Unadjusted prices are used by default: they are what actually traded. Bars come from the local store and are downloaded from Massive only when missing.

2. Strategy

DEMO: N-bar breakout (demonstration only). Demonstration strategy only. It is not a validated trading strategy, not a recommendation, and not the trader's strategy. Parameter values are arbitrary examples.

to
intraday data only

3. Execution assumptions and costs

All amounts are illustrative examples, not any broker's actual pricing. Change them to match the account being modelled.

Commissions and fees

Short selling

With an empty list, short availability is assumed for every symbol: the platform has no historical locate or borrow data and does not invent any.

4. Run

Saved runs

Each saved run keeps its settings, strategy parameters, engine version and a fingerprint of the exact data it used, so it can be re-run and compared. Market data is not copied into the database.
