And why in the world would you want to trade in the pre-market when the spread is larger??
Exactly that is the point ;-) Pre-market has larger spread and less action so you can easily sell to yourself without losing on spread. Remember there is no market order during extra-hours.
Take an example - ABC has current bid/ask of 10.14/10.30, so you put an order in A1 as limit-sell @ 10.20 and order in A2 as limit-buy order of 10.21

You end up paying double the number of commissions as well as double the number of B/A spreads (slippage)...not to mention price change risk in the time it takes to execute the 2nd trade.
If your commission is ultra-low, this is not an issue - right? 3 * 2 < 7 ;-)
This technique should work great for small position traders who are otherwise limited by PDT and sometime forced to hold the risky position overnight.
Let me explain it by example.
My first buy is SRS @ 46; it hit stop @ 44 within an hour - one DT over. Similar happened with my other buy DXO @ 3.2; it hit stop @ 3.1 - second DT over.
With only 1 life-line remaining, now I'm scared. I might avoid putting stop for my third trade and hold it overnight.
Now re-visit the revised scenario.
First buy is SRS @ 46 in A1 and set a stop-sell-short @ 44 in A2. stop executed and my loss is locked without triggering any day trade.
If my next order is for different stock then I can even swap the account; example - buy DXO in A2 and set the stop-sell-short in A1.
I can buy SRS again @ 38 in A1 and possibly sell higher on re-bound @ 43 by selling-short in A2.
Next day, I settle all SRS in one trade so, effective commission is only 50% more.
No day trade ever
