Moving Average Crossover

A trend-following strategy: buy when a faster moving average crosses above a slower one, and exit when it crosses back below. Simple rules, but it struggles in sideways markets.

Slav: "Two lines cross and I click buy? Finally, a strategy my cat could follow." Max: "Your cat would also ignore the stop loss."

The idea

A moving average (MA) is the average closing price over the last X candles, drawn as a line on the chart. A short MA (for example 20 days) reacts quickly; a long MA (for example 50 days) reacts slowly.

When the fast MA crosses above the slow MA, recent prices are rising faster than the longer trend: a possible start of an uptrend. When it crosses below, a possible downtrend.

When it works best

  • Strong, long trends
  • Markets with clear directional moves

When it fails

  • Sideways (ranging) markets: the lines cross back and forth and create many small losses, called "whipsaws"
  • Sudden news moves: moving averages are slow to react

Entry rules (long example)

  1. Use the daily chart with a 20-period and a 50-period moving average.
  2. Wait for the 20 MA to close above the 50 MA.
  3. Optional filter: price is also above the 200 MA (the long-term trend is up).
  4. Enter at the open of the next candle.

Stop loss

Below the most recent swing low before the crossover, or a fixed distance you have tested. Calculate your position size so this stop equals your maximum risk (for example 1% of your account).

Exit / take profit

  • Exit when the 20 MA crosses back below the 50 MA, or
  • Take partial profit at 2× your risk and let the rest run until the cross-back

Example (fictional)

Sunny Bikes is at $20. The 20 MA crosses above the 50 MA. Slav buys at $20.20, with a stop at the recent swing low of $18.80 (risk $1.40 per share). Weeks later the trend continues and the 20 MA crosses back below the 50 MA at $24.10. He exits: +$3.90 per share, about 2.8 times his risk. The next two signals are whipsaws that lose about 1× risk each. This is normal for trend-following: several small losses, occasional big wins.

Pros

  • Clear, objective rules: easy to test
  • Catches large trends
  • Works on many markets

Cons

  • Late entries and late exits (MAs lag)
  • Many false signals in sideways markets
  • Long losing streaks are possible

Common mistakes

  • Changing the MA settings after every loss
  • Trading every cross, even in a flat, choppy market
  • Moving the stop loss further away "just this once"

Checklist before the trade

  • The cross happened on a closed candle
  • The market is trending, not flat
  • Stop loss is placed and position size calculated
  • I accept this trade could be one of the whipsaws
