### Comment:
Not true, Max Gain + Max Loss =width of the spread. The closer he sells his strike to the current trading price more credit he brings in but greater chance the spread could move against him. In theory he could sell a $5 wide spread for $4.99 credit and have a max loss of $0.01 but at that point the spread is probably under water and he would just be throwing away the $0.01 
  
 Edit: your max gain on a credit spread is whatever you sell it for.
