Was Shakespeare a trader?

No I didn't write this but you should read it:

Weary with toil, I haste me to my bed,
For then my thoughts--from far where I abide--
The dear repose for limbs with travel tired;
Intend a zealous pilgrimage to thee,
And keep my drooping eyelids open wide,
Looking on darkness which the blind do see:
Save that my soul's imaginary sight
Presents thy shadow to my sightless view,
Weary with toil, I haste me to my bed,
The dear repose for limbs with travel tired;
But then begins a journey in my head
To work my mind, when body's
Which, like a jewel hung in ghastly night,
Makes black night beauteous, and her old face new.
Lo! thus, by day my limbs, by night my mind,
For thee, and for myself, no quiet find.
 
I think that things that are constants are very reassuring.  That when involved with mental work we do that all day and then lay awake at night thinking about what we have already done and what we will do tomorrow.  Traders seem to be like that.  When the market is open they are on high alert and instead of walking away, most seem to think and plan.  Just my impression.  By day my limbs, by night my mind, for you and me there is no solitude.
