RSI Momentum
Have apple prices risen more than they have fallen?
Keep the same apple prices, but look at their changes. A move from $2 to $3 adds $1; a move back to $2 loses $1. RSI compares upward and downward movement on a scale from 0 to 100.
Separate rises from falls
In the first 14 daily changes of our apple year, there are three $1 rises, two $1 falls and nine unchanged days. Total upward movement is $3; total downward movement is $2.
Turn those changes into a score
For this first calculation, $3 of the $5 total movement is upward. That gives an RSI of 60. Later scores update smoothed average gains and losses using Wilder's method, rather than restarting this simple tally each day.
Check positive momentum
This site counts RSI above 50 as Yes. A reading of 60 fits, and readings above 70 remain Yes. The 70 line is an overbought reference, not a score ceiling. RSI is not a 60% chance of a price rise.
Example
One year at the apple stall
The upper chart shows apple prices. The lower chart shows RSI, with the 50 score floor and a separate 70 overbought reference.
- Apple price
The apple-price momentum score
- RSI(14)
- Site's lower boundary
- RSI 70 reference
On day 15, the first 14 changes give RSI 60: three dollars of gains against two dollars of losses. This is above the site's 50 floor. RSI can later rise above 70 and still count Yes.
Prices are whole dollars. Averages, scores and returns are shown as approximate whole numbers; MACD gaps use cents. The lines and rule comparisons use the full calculation. A moving average begins only when enough days are recorded.
| Example value | Site result |
|---|---|
| 40 | No |
| 49 | No |
| 50 | No |
| 55 | Yes |
| 70 | Yes |
| 80 | Yes |
What the lines mean
The upper chart shows apple prices; the lower chart shows RSI from those prices. The green line marks the score floor at 50. The amber line at 70 is a familiar overbought reference, not a score ceiling. RSI has no dollar unit.
RSI Momentum
This site uses the following calculation to check whether this indicator signals a Bitcoin bull run. Each Yes adds one point to the Bull Run Score, out of five.
Yes when RSI(14) is above 50. Readings at or below 50 are No when inputs are available. There is no upper limit: a high RSI can occur during a strong uptrend.
RSI(14) > 50
What this cannot tell you
RSI above 50 describes positive recent momentum, not proof of a bull run or a forecast. Very high readings can persist while prices rise.
An indicator needs enough recorded observations before it can be evaluated. Missing inputs mean unavailable, not No.
These are independent rules. They can disagree, and a Yes is not a forecast or a recommendation.
