then adjust the default number to whatever you like.
just make sure you select daily, or the timeframe you want.
note: that above 'source' button can be tweaked a bit too for different results so I cant be certain what the most relevant setting is.
another way on invest is click 'technical'
again, depending on your timeframe selected (here im watching hourly, not daily), you will see MAs and a whole host of others you may never understand or use
-just dont always believe their buy and sell signals. use your brain
