The prices
The averages
The 10-close simple average (99.68) is above the 20-close one (99.12) by 0.56%.
- The cross
- The fast average last crossed above the slow one 4 closes ago, at 99.80.
- The price
- The last close of 99.33 is 0.35% below the fast average and 0.21% above the slow one.
- Read it with care
- A cross confirms a move after it has started; in a sideways market the averages cross back and forth and each cross costs a spread.
The last 5 closes. The last close is marked.

Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it.

Two averages, one rule
A moving average smooths the closes so the direction shows. A crossover rule uses two: when the fast one rises above the slow one the recent closes are higher than the older ones, and the reverse when it falls below. On daily closes the 50 crossing the 200 is called the golden cross going up and the death cross going down.
Simple averages weigh every close the same; exponential and weighted ones lean on the latest closes, so they turn sooner and also flip more often. Every crossover rule trades late, and in ranges it pays the spread for each false cross: test it on your market with costs first. See what a single average did over a century in the trend filter lesson, and compare with the MACD calculator, which is the gap between two exponential averages.
