OK. Thanks for the correction. I apologize.
So, you are saying one can have longer time frame but not larger size?
Hmm... So, instead of the typical institutional size of 10K-50K-100K-1M shares and holding on for months then one is allowed to hold maybe just 1000-5000shares for a few weeks?
Even then it's not too bad if you have a portfolio of maybe 5-10 stocks that you want to swing trade for 5-10pts move each with 1000-5000shares position. Maybe I would give it another try.. 
thanks for the clarification!

Let's define risk
Your risk on any trade is this
our entry price minus your stop times the # of shares you buy
Risk = (E-S) * # of shares
So let's say you are buying a 100 dollar stock.
If you are using a larger time frame that means a stop further away.
So (100 - 75)* 1000 = 25,000
now take your example with the larger scale you suggested
( 100-75)* 100000 = 2,500,000
now that loss can be small or big but it depends on your account size. A fund that is managing 50 billion than a 2.5 million dollar hit is just the cost of a trade or 2.
On a 3 million dollar account it would be devasting.
I can play with that formula all you want.
A lot of traders at professional firm take large share positions
but....they have extremely tight stops
such as (100-99.50)*4000= 2000 so there risk is limited by having the tight stop.
