Day trading platforms are the set of tools that a day trader uses to execute trades, analyse the market, and manage risk. The platform is the day trader's cockpit, and the quality of the platform determines the efficiency and the execution quality of the day trader's activity. A good day trading platform is fast, reliable, and well-equipped; a bad platform is slow, unreliable, or missing the tools the day trader needs.
The difference between a day trading platform and a standard brokerage platform is the level of sophistication. The day trading platform offers direct market access (DMA), advanced charting with multiple time frames, Level 2 data (order book depth), hotkeys for one-click trading, and a customisable interface. The standard brokerage platform offers basic charting, delayed data, and a slower execution through the broker's internalisation.
The essential tools
The execution interface is the most important tool. The day trader needs to enter and exit positions in seconds, and the platform must provide a fast and reliable order entry interface. The interface should support hotkeys (one-key shortcuts for buy, sell, buy-to-cover, sell-short, and the order types), and the interface should allow the trader to set the order size, the order type, and the limit price with a single click.
The charting interface is the second most important tool. The day trader needs to see the price action on multiple time frames (1-minute, 5-minute, 15-minute, 1-hour), with the indicators the trader uses (moving averages, RSI, MACD, volume profile, VWAP). The charting should be fast and accurate, with no lag between the market data and the chart.
The Level 2 data (the order book depth) is the third most important tool. The Level 2 data shows the buy and sell orders on the exchange at each price level, and the day trader uses the data to identify the support and resistance levels, the order flow, and the market manipulation. The Level 2 data is essential for a day trader who is trading with size or who is trading on a short time frame.
The platform types
The professional platforms are the ones designed for institutional and high-volume retail traders. The examples are DAS Trader, Sterling Trader Pro, and Lightspeed. The platforms offer direct market access, Level 2 data, hotkeys, and a customisable interface. The platforms are expensive ($100-$500 per month) and require a minimum deposit ($10,000-$25,000).
The semi-professional platforms are the ones designed for active retail traders. The examples are TradeStation, NinjaTrader, and TD Ameritrade's thinkorswim. The platforms offer advanced charting, hotkeys, and some Level 2 data, and they are available at a lower cost (free with a minimum deposit, or $50-$100 per month). The platforms are a good choice for a day trader who is not yet trading at the professional level.
The retail platforms are the ones designed for occasional traders. The examples are the mobile apps and the web interfaces of the discount brokers. The platforms offer basic charting, delayed data, and a slower execution, and they are free with no minimum deposit. The retail platforms are not suitable for day trading in fast markets.
The market data packages
The day trader needs real-time market data from the exchanges. The data includes the Level 1 data (the bid, ask, last, volume, and VWAP) and the Level 2 data (the order book depth). The data is provided by the exchanges, and the broker passes the data to the trader.
The market data packages cost $50-$200 per month for a retail trader (US equities data from NYSE and Nasdaq is $10-$50 per month; Level 2 data is $10-$50 per month; options data is $10-$50 per month; futures data is $10-$50 per month). The cost is a real drag on the day trader's profitability, and the cost should be factored into the day trader's budget.
The execution quality
The execution quality is a function of the platform's speed and the broker's routing. A platform with direct market access routes the order directly to the exchange or the market maker, and the execution is fast and transparent. A platform without DMA routes the order through the broker's internaliser, and the execution is slower and less transparent.
The day trader should compare the execution quality across platforms by looking at the fill rate, the slippage, and the order rejection rate. The platform with the highest fill rate and the lowest slippage is the platform that provides the best execution quality.
Common questions about day trading platforms
Can I day trade on a mobile app? Most mobile apps are not designed for day trading in fast markets. The mobile interface has lower latency, less charting functionality, and slower order entry. A desktop platform is the standard for day trading.
Is a free platform good enough? A free platform (the broker's standard web interface) is usually not good enough for day trading in fast markets. The free platform has delayed data, slower execution, and limited order types. A paid platform with direct market access is the standard.
What is the cost of a day trading platform for a beginner? The cost is $50-$500 per month for the platform and the data packages, plus the broker's commission on the trades. The total monthly cost for a basic day trading setup is $100-$200 per month.
