Hello,

I kwow it is profitable to buy when the price is low and sell when the price is high.
What I see in the currency exchange I am trading on are 24 hr percentages.
Sometimes the percentages show a 'minus' -, and sometimes they show a 'plus' +.

Is it a goog idea (when you think in terms of profit) to buy a coin when the percentage shows for example -5% and then sell when the percentage shows +5%?

Thanks
