# Building blocks

Strategies in Quanorix are **typed rule trees** built from **building blocks**: classic indicators, operators, and price-action / structure blocks (SMC, FVG, ORB, and similar).

## What it means for you

| Phase          | Role of blocks                                                                       |
| -------------- | ------------------------------------------------------------------------------------ |
| **Generation** | The engine combines enabled blocks into entry conditions (and HTF context when used) |
| **Backtest**   | Each block has fixed causal semantics in the engine                                  |
| **MQL export** | EAs only ship when coverage allows: *supported* / *approximate* / blocking           |

Before live trading: read the coverage report in [Export bots](/en/export/mt4-mt5).

## Families (customer level)

Without listing the full internal catalog:

* **Indicators** — averages, oscillators, volatility (ATR), etc.
* **Price / structure** — swings, S/R, trends.
* **Session / time** — hour filters and Asia/London/NY presets (see [Sessions](/en/settings/sessions-timezones)).
* **SMC / liquidity** — order blocks, BOS/CHOCH, FVG / IFVG, sweeps (as available).
* **Patterns** — e.g. ORB, bull flag, CRT, or others enabled in your build.

**Settings → Blocks** enables or disables families for **new** searches.

## Warmup and HTF

* Many indicators need **warmup bars**; the engine accounts for them when evaluating.
* Higher-timeframe context aligns to entry; with HTF, **entry edge** is often preferable ([multi-TF](/en/generator/presets-mtf)).

## Export-ready

A strategy is safer to export when:

1. Its blocks are **supported** (or you knowingly accept *approximate*).
2. Costs and TZ are calibrated ([realism](/en/concepts/fill-realism), Sessions).
3. It passed at least a reasonable OOS / walk-forward check.
