# Subscriptions

Subscriptions, also known as Strategy Subscriptions, are what allow you to connect a strategy to a broker and to control what kind of orders get sent to the broker. A strategy subscription *copies* the default settings of the Strategy and can essentially have its own settings. This is a powerful feature because it allows you to define different rules for different accounts all executed from the same single signal.

## Create a Subscription

Once you have connected your broker and created a strategy, now you are ready to subscribe to the strategy to connect it to your broker.

1. Navigate to **Subscriptions** and click the **New Subscription** button at the top right.
2. Then, choose the strategy from the list that you want to subscribe to and click the **Subscribe** button.
3. Next, choose the broker from the list that you want to connect your strategy to and click it. A confirmation modal will pop up, check the **Confirm** checkbox and click the **Confirm** button.
4. Now your strategy subscription is created, but has not been enabled yet. Review the settings for your strategy subscription and click **Save** if you make any changes.
5. Once you are ready, click the green **Enable** button to enable your strategy subscription. Now, when TradersPost receives an alert to your webhook, a trade will be executed and orders sent to your broker.

## What happens when a trade is executed?

1. **Cancel Open Orders** - Open orders for the ticker will be canceled if one of the following is true
   * There is no open position for the ticker.
   * There is an open position and it is on the opposite side of the signal. For example you have an open long stocks position and you receive an `action=sell` signal. Any take profit or stop loss sell orders will be canceled before exiting the long stocks position.
   * The signal is an explicit cancel signal where `action=cancel`.
2. **Exit Current Position** - Any open position for the ticker in the signal will be exited based on the configuration details in your subscription. For example, if you have a long stocks position open for AMD and you get an `action=sell` signal, the long position will be closed with a sell order.
3. **Enter New Position** - A new position will be entered with an order based on the configuration details in your subscription.

## Architecture

We separate the Brokers, Strategies, Subscriptions and Webhooks at an architecture level to give more flexibility. Some of the benefits are:

* You can easily change the webhook that powers a strategy with zero disruption to the strategy subscribers.
* You can connect a strategy to multiple different brokers with different settings.
* You can connect a strategy to both a paper and live account at the same time and run them in parallel.
