Fix and add money management to my EA

I have a EA that is grid based and it hedges on some trades. I need to add money management and control the way the EA picks and chooses the lot size. Right now when the EA hedges it chooses a Small and Large lot size. I had someone modify the EA so it allows you to choose Large and Small lot size and Max allowed lot size. There was some problems when adding that functionality, when the EA hit the max lot size it would continue to open indefinitely Max lot size and it wouldn't go back to the normal lot sizes. Also The Large and Small lot size portion when enabled only works on some trades and not on all trades. I need someone to override the EA's logic portion that picks lot size so when money management is enabled the EA will obey the new rules for lot size.  

One Idea I had with the Large Lot Size is once the EA opens the Max lot size the next trades will reset and go back to the default lot sizes the EA uses when first enabled. For instance let's say I am using 0.01 for Small Lot size and 0.04 for the Large lot size and I set the Max Lot Size to 0.10 Once the EA hits 0.10 the next trades will go back to the manually inputted Large and Small lot size and the EA will start trading as if it was put on the chart fresh. You will need to change internally how the EA picks lot size so the EA doesn't malfunction when money management is enabled. 

It's ok to tweak the logic to get money management to work and fix the concerning issues about the EA repeating Max lot size forever and the Large and Small lot size only working on some trades and not all trades. 

I also one more bug when money management is enabled the EA sometimes doesn't close trades and keeps them open forever. This bug should be addressed also. 

I also want to add Max Stop Loss. This will be max allowed Stop Loss per trade. 

Again when money management is disabled the EA will function normally before the money management was added 

Before bidding I would like you to review the EA with the money management enabled and the original EA so we can see how to fix these bugs so the EA doesn't malfunction.
