Can we please get a better explanation how the 2 stock bots work?

So static ping pong  = you set your buy price and sell price and the bot keeps the limit order ...

start > Set 10 buy Limit  @ $100 > once trade happen > set 10 sell Limit @ 200 > once trade happen > wait to rebuy back  back 10 @ $100 ....so on

when does margin trading it do the same thing but sells 10 extra so now it in a short position?


How does margin maker work?
