Thinkorswim's powerful charting and analytical tools support a wide range of trading strategies. Here are three popular approaches that can be implemented on the platform.
This strategy uses moving averages to identify and follow trends. A common setup is the crossover of a short-term moving average (e.g., 20-period) above a long-term moving average (e.g., 50-period) as a buy signal, and the reverse as a sell signal. Thinkorswim allows you to overlay these indicators on your charts and set alerts when crossovers occur.
Breakout trading involves identifying key support and resistance levels and entering trades when price breaks through these levels. Thinkorswim's drawing tools allow you to mark these levels on the chart. You can set alerts or use stop-entry orders to automatically enter trades when a breakout occurs.
Scalping is a high-frequency strategy that aims to capture small price movements. Thinkorswim offers tick charts and Level 2 (order book) data, which are valuable for scalpers. This strategy requires fast execution and tight risk management, and it is generally recommended only for experienced traders.
Maria, a mid-level trader, uses Thinkorswim to trade EUR/USD. She identifies a bullish crossover of the 20-day and 50-day moving averages. She places a buy stop order above the recent swing high, sets a stop-loss at the swing low, and a take-profit at a 2:1 risk-reward ratio. She uses the Thinkorswim bracket order feature to attach both the stop-loss and take-profit to the entry order. The trade triggers and moves in her favor, hitting the take-profit within three days.
