Append `?lang=csharp` to this URL for the C# version of this page. ## Introduction The Lean CLI supports live trading on your local machine or in QuantConnect Cloud, which makes the transfer from backtesting to live trading as seamless as possible. You must [log in](https://www.quantconnect.com/docs/v2/lean-cli/initialization/authentication.md#02-Log-In) using your QuantConnect account to deply your algorithm on your local machine or in QuantConnect Cloud. This page contains instructions on how to start live trading with the Quant Bridge brokerage. If the [Lean Configuration file](https://www.quantconnect.com/docs/v2/lean-cli/initialization/configuration.md#03-Lean-Configuration) in your [organization workspace](https://www.quantconnect.com/docs/v2/lean-cli/initialization/organization-workspaces.md) contains values for some of the command options, the CLI skips some of the prompts. The LEAN CLI integrates with the Bloomberg Desktop API (DAPI) to get data for research, backtests, optimization, and live trading or through your existing Bloomberg data subscriptions. In addition, you can route live trading strategies and and UAT paper trading through Bloomberg order routing via the EMSX network. To use the CLI, you must be a member in an [organization](https://www.quantconnect.com/docs/v2/cloud-platform/organizations/tier-features.md) on a paid tier. ## Asset Classes Quant Bridge supports trading the following asset classes: - [Equities](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/us-equity.md) - [Equity Options](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/equity-options.md) - [Index Options](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/index-options.md) - [Futures](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/futures.md) ## Data Feeds Quant Bridge with the LEAN CLI lets you source historical data from Bloomberg and save it onto your desktop computer for backtesting as within your license permissions from Bloomberg. The Bloomberg API includes up to six months of history in low resolutions like second and minute resolutions. ## Orders Quant Bridge enables you to create and manage Bloomberg™ orders. You can also use the LEAN CLI with the Quant Bridge integration to test paper trading with LEAN. In this case, LEAN models order fills using the live tick data feed from Bloomberg™. ### Order Types The following table describes the available order types for each asset class that Quant Bridge supports: | Order Type | Equity | Equity Options | Futures | | --- | --- | --- | --- | | [MarketOrder](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-types/market-orders.md) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | | [MarketOnOpenOrder](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-types/market-on-open-orders.md) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | | | | [LimitOrder](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-types/limit-orders.md) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | | [StopMarketOrder](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-types/stop-market-orders.md) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | | [StopLimitOrder](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-types/stop-limit-orders.md) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ### Time In Force Quant Bridge supports the following [TimeInForce](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-properties.md#03-Time-In-Force) instructions: - `DAY` - `GOOD_TIL_CANCELED` - `good_til_date` ### Get Open Orders Quant Bridge lets you [access open orders](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-management/transaction-manager.md). ### Monitor Fills Quant Bridge allows you to monitor orders as they fill through [order events](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-events.md). ### Updates Quant Bridge doesn't support [order updates](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-management/order-tickets.md#04-Update-Orders). ### Cancellations Quant Bridge enables you to [cancel open orders](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-management/order-tickets.md#05-Cancel-Orders). ### Handling Splits If you're using raw [data normalization](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/us-equity/requesting-data.md#11-Data-Normalization) and you have active orders with a limit, stop, or trigger price in the market for a US Equity when a [stock split](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/us-equity/corporate-actions.md#02-Splits) occurs, the following properties of your orders automatically adjust to reflect the stock split: - Quantity - Limit price - Stop price - Trigger price ## Fees Orders filled with Quant Bridge are subject to the fees of the Bloomberg™ Execution Management System and your prime brokerage destination. To view how we model their fees, see [Fees](https://www.quantconnect.com//docs/v2/writing-algorithms/reality-modeling/brokerages/supported-models/quantconnect-paper-trading#06-Fees). ## Historical Data When LEAN taps into Bloomberg™ via Quant Bridge, it can run backtests and research notebooks with rich historical data sourced from the Bloomberg™ Terminal. LEAN provides accurate slippage, spread, and transaction fee models for realistic backtesting. All models are customizable to adapt to your strategy requirements. Historical data is cached locally in an efficient format for quick backtesting in the LEAN engine. If you request intraday historical data, you can request data from within the last 6 months. Historical open interest and custom data isn't available. ## Compliance Bloomberg™ is not affiliated with QuantConnect, nor does it endorse Quant Bridge. QuantConnect requires a Trading Firm or Institutional license to use the Quant Bridge integration. The following rules apply: - All users of the integration must hold a Bloomberg License to be defined as an "Entitled User". - All data accessed via the Bloomberg Desktop API must remain on the host computer. The Bloomberg Terminal and the LEAN instance must be on the same computer. The following table shows the activities each of the Bloomberg technologies support: | Technology | Research | Backtesting | Paper Trading | Live Trading | | --- | --- | --- | --- | --- | | Desktop API | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | | B.PIPE | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ## CLI Commands Execute the [CLI](https://www.quantconnect.com/docs/v2/lean-cli.md) commands in the following sections to interact with Quant Bridge. If you need further assistance, see the [CLI Reference](https://www.quantconnect.com/docs/v2/lean-cli/api-reference.md). ### Run Local Backtests Launch local backtests with data from the Bloomberg Terminal Desktop API.

Follow these steps to start local live trading with the Quant Bridge brokerage: 1. [Log in](https://www.quantconnect.com/docs/v2/lean-cli/initialization/authentication.md#02-Log-In) to the CLI if you haven't done so already. 2. Open a terminal in the [organization workspace](https://www.quantconnect.com/docs/v2/lean-cli/initialization/organization-workspaces.md) that contains the project. 3. If your algorithm trades US Equities, Options, or Futures, [purchase and download](https://www.quantconnect.com/docs/v2/lean-cli/datasets/quantconnect.md) the QuantConnect datasets that LEAN uses for the asset class. Crypto, Forex, and CFD algorithms can skip this step. The following table shows the datasets for each asset class: | Asset Class | Datasets | | --- | --- | | US Equity | [US Equity Security Master](https://www.quantconnect.com/datasets/quantconnect-us-equity-security-master/cli), to get adjusted prices. Without it, your algorithm uses raw prices. | | US Equity Options | [US Equity Security Master](https://www.quantconnect.com/datasets/quantconnect-us-equity-security-master/cli) and [US Equity Option Universe](https://www.quantconnect.com/datasets/quantconnect-us-equity-option-universe) | | US Index Options | [US Index Option Universe](https://www.quantconnect.com/datasets/quantconnect-us-index-option-universe) | | US Futures | [US Futures Security Master](https://www.quantconnect.com/datasets/quantconnect-us-futures-security-master/cli) and [US Future Universe](https://www.quantconnect.com/datasets/quantconnect-us-future-universe) | | US Future Options | [US Futures Security Master](https://www.quantconnect.com/datasets/quantconnect-us-futures-security-master/cli), [US Future Universe](https://www.quantconnect.com/datasets/quantconnect-us-future-universe), and [US Future Option Universe](https://www.quantconnect.com/datasets/quantconnect-us-future-option-universe). To get access, [contact us](https://www.quantconnect.com/contact). | If your algorithm uses [universe selection](https://www.quantconnect.com/docs/v2/writing-algorithms/universes/key-concepts.md), also download the universe dataset, such as the [US Equity Coarse Universe](https://www.quantconnect.com/docs/v2/lean-cli/datasets/quantconnect/us-equity-coarse-fundamental.md) or [US ETF Constituents](https://www.quantconnect.com/docs/v2/lean-cli/datasets/quantconnect/us-etf-constituents.md). 4. Run `lean live deploy ""` to start a live deployment wizard for the project in `. / ` and then enter the brokerage number, **10**. ``` $ lean live deploy "My Project" Select a brokerage: 1) Paper Trading 2) Interactive Brokers 3) Tradier 4) OANDA 5) Bitfinex 6) Coinbase Advanced Trade 7) Binance 8) Zerodha 9) Samco 10) Quant Bridge 11) Trading Technologies 12) Kraken 13) Charles Schwab 14) Bybit 15) TradeStation 16) Alpaca 17) Tastytrade 18) Eze 19) dYdX 20) Webull 21) Public 22) Clear Street ``` 5.
