Nobody wants to be monitoring the prices all day with the cursor on the sell button just waiting to click the mouse, so how do you decide when to sell?
If you set up an open order with a low target price, you'll be disappointed when the price climbs well above your target price.
If you set up an open order with too high a price, you might not sell at all.
What's your strategy?
Depends on how much a person wants for his ROI's. If you are contented with small profits then sell when prices starts to go up but if you want a big profit then you just hold and wait till prices would go sky high.
