RSI Filter: Sell Puts on Oversold Stocks, Calls on Overbought

Use the 14-day RSI filter to time wheel entries — sell CSPs after pullbacks (low RSI) and covered calls after rallies (high RSI).

What RSI tells you

The Relative Strength Index (RSI) is a 0–100 momentum oscillator. Conventionally:

  • Below 30 = oversold (potentially bouncing)
  • 30 – 70 = normal range
  • Above 70 = overbought (potentially pulling back)

For wheel traders, RSI is a beautiful entry-timing tool:

  • Sell cash-secured puts when RSI is low (you're getting paid to bet on a bounce).
  • Sell covered calls when RSI is high (you're getting paid to bet on a pullback).

Where to find it

The RSI filter is in the sidebar of both screeners. It's a 0–100 range slider keyed to the 14-day RSI of the underlying stock.

Recommended ranges

For cash-secured puts (look for oversold):

RSI rangeMeaning
0 – 30Strong oversold — premium-rich pullback
30 – 45Mild pullback
45 – 100Probably skip for CSP timing

For covered calls (look for overbought):

RSI rangeMeaning
70 – 100Strong overbought — premium-rich rally
55 – 70Mild rally
0 – 55Probably skip for CC timing

A worked example

You want to find puts on oversold names with rich premium:

  1. Open the Put screener.
  2. Set RSI to 0–35.
  3. Set Delta to −0.30 to −0.15.
  4. Set Volume ≥ 100 and Earnings Excluded = on.
  5. Sort by Yield descending.

This is essentially the RSI Oversold preset without the preset wrapper.

Pairing RSI with the rest

  • RSI + IV — oversold and high IV = the classic wheel entry.
  • RSI + Moving Average — confirm the pullback is to a meaningful support level (50- or 200-day MA).
  • RSI + Earnings — make sure the oversold isn't a pre-earnings selloff.

Common mistakes

1. Buying every RSI 30. Oversold can stay oversold for weeks during a real downtrend. Confirm with fundamentals before you commit.

2. Only using extreme thresholds. The strict 30/70 levels are conventional, not magic. Many traders use 35/65 to catch more setups.

3. Ignoring time frame. The screener uses 14-day RSI. Daily RSI tells a very different story than weekly RSI — keep that in mind for longer holds.

Frequently Asked Questions

What RSI level is best for selling cash-secured puts?

Most wheel traders look for RSI between 0 and 35 on the underlying stock — oversold conditions where premium is rich and the stock has room to bounce.

Does RSI work for covered calls too?

Yes. Use the inverse: RSI between 65 and 100 on a stock you own makes for high-premium covered calls because the market is paying up for the assumption a pullback is coming.
