3: Customize the Settings

To fine-tune the stochastic oscillator:

1. Click the Edit Studies button (beaker icon).
2. Find the “StochasticSlow” study and click Settings (gear icon).
3. Modify the following:
   • %K Period (Default: 14)
   • Slow %K (Default: 3)
   • %D Period (Default: 3)

For faster signals (intraday):

• Try %K: 5, Slow %K: 3, %D: 3

For swing trading:

• Use 14,3,3

You can also:

• Change line colors
• Add upper/lower bands (typically 80 and 20)

Step 4: How to Use It for Trading

The crossover of the %K and %D lines gives trading signals:

• Buy Signal: %K crosses above %D below 20
• Sell Signal: %K crosses below %D above 80

You can also use divergence or combine with MACD, trendlines, or support/resistance for added accuracy.

Step 5: Set Alerts for Crossovers (Optional)

ThinkorSwim allows you to set alerts:

1. Right-click on the stochastic indicator area.
2. Select Create Alert.
3. Set conditions like %K crossing %D or entering/exiting overbought/oversold zones.
4. Choose your notification method (sound, email, or SMS).

This helps you act on signals without watching the screen all day.

Tips for Better Results

• Avoid trading in isolation – confirm with volume or trend filters.
• Use multiple timeframes – get trend direction from the higher timeframe, then trade signals on a lower one.
• Backtest your strategy using TOS’s “thinkBack” tool.
