## Principle

• It does not predict a price up or down
• It only notify when there is a rise on a coin. Price change is > 1.5% and volume change > 2%
• It gets data on Poloniex page
• The bot fetch data every 3 minutes

## Examples

Ripple 1.0559% rises vs previous price. Volume: 22.6 btc. 24h Volume: 61960.10461694 btc. Rise streak: 1. Rise percentage (recent 100): 50.5%. Trend: 1.05% -0.73% -0.83% -0.13% -1.88% -1.23% 1.25% 0.63% -1.76% -1.5% . Watch & buy?

• Rise 1.0559% to previous price in btc
• Volume: 22.6 btc (estimated, maybe incorrect because Poloniex does not supply)
• 24h Volume
