Step-by-Step Guide

Step 1

Set Up Your Alpaca Paper Trading Account

Before placing any trades, you need access to the paper environment.

Go to alpaca.markets and sign up for a free account.

Generate your API keys (Key ID and Secret Key). These will allow you to connect trading bots, scripts, or simply use Alpaca’s terminal or third-party platforms.

Step 2

The Technical Setup – Define Your Trade

Before executing anything, you need a reason to enter.

Trend confirmation: Are you trading with or against the trend?

Key levels: Identify support (for longs) or resistance (for shorts).

Step 3

Risk Management – Position Sizing First

In Alpaca Paper Trading, you can practice the 1% Rule without consequences—but treat it as mandatory.

Stop loss distance (in dollars or percentage)

Position size = Risk amount ÷ Stop loss distance

Step 4

Executing the Trade on Alpaca

Now we move to actual execution. Alpaca supports both REST API and manual execution via their dashboard or connected platforms like TradingView.

Option A: Manual Execution via Alpaca Dashboard

Log into your Alpaca Paper Trading dashboard.

Step 5

Setting Stop Loss and Take Profit in Alpaca

Alpaca supports bracket orders, which attach a stop loss and take profit to your initial order.

After your position is open, go to the Positions tab.

Place a Limit Order for your take profit.

Step 6

Monitoring and Managing the Trade

Once your trade is live in Alpaca Paper Trading:

Walk away if your analysis is solid. Over-monitoring leads to emotional decisions.

Adjust stops manually if price moves favorably—you can submit new stop orders anytime.

Step 7

Review and Analyze

After the trade closes (win or loss), Alpaca Paper Trading keeps a full history.

This review process is where real improvement happens.
