We can't add contracts to Opening Gap systems and that's understood.
We cannot add contracts to CL systems, because they have huge leverage and that's understood.
We cannot add contracts to 2 WITH IT TREND GBP systems because they are too similar among each other.
We cannot add contracts to GOLD because it has a big leverage.
We should not add contracts to YM and ES but trade both contracts in all cases: same system traded on two different futures is a good thing (regardless of which future trades it better, because there's a slight random difference).
The only contracts to be increased to 2 contracts are on 2 GBL, 1 ZN (one other system is not good enough), 1 GBP, 1 EUR systems. And 3 contracts for the best system I have, the ZN_ON_2. Let's see what happens to the equity curve. 20 systems will be traded and 6 of them will be allocated more than 1 contract.
Here's the final combination of contracts and systems:

The maximum drawdown will be 3 months long and will go 13k deep.
If instead we do not allow more than 1 contract, here's what happens:

The drawdown is just 10k and it lasts 3 months, too. I would much prefer to add contracts the way I said.
Let's consider that some of these systems started trading more recently so the one year of forward-testing only means 6 months or one week in some cases (CL_ID_3). On the other hand, I can't expect all these systems to keep on performing as well in the future. Given this combination of systems and contracts, I could expect about 10k per month, given a needed capital of 30k, which could realistically guarantee that all signals are traded (it's impossible for all signals to happen at the same moment), even when that 13k drawdown should occur (which represents a 40% of the account, and that's hard to take).
Realistically I have systems that could make about 30% a month, which is awesome, but since I've blown out my accounts endlessly for the past 13 years I will have to rely on outside investors now - whose advantages, other than capital, I already mentioned. But the disadvantage is that I can't quit my job yet. The advantage maybe is that if it were all my money I would blow out my account again by second-guessing the systems. I've never been so disciplined as I have in the past 3 months, being monitored by outside investors. A disadvantage is having to let other people know about your strategies, which I would have preferred to keep secret. There are advantages and disadvantages in working as a team: certainly I am part of the best team I could ever have hoped for. People who don't get into arguments and people who appreciate my work and are polite. I'm being monitored and coached and this is also good.
I could also take out another loan or ask others and do it all on my own. But I don't have the courage to go it alone, because of all my past failures in managing any sums of money: large or small. I blew out small 3k accounts and I blew out 30k accounts. And it was all my money. With the investors, I've gotten upset, I've written polemic emails, but not once in the last 3 months have I not followed the systems. And the results were rewarding such behaviour and such partnership. The most we were down was 2k and now we're up again. In the meanwhile I've lost thousands on my own account. The investors protect me from myself.
On the other hand, of course, I would much prefer if my dad told me "here's 200k, do whatever you want". But he never said anything like that. If he did that, i think I would quit my job and I would trade my own capital using the money management and rigor i was taught by the investors once again. I still don't know if I've fully learned it though. I don't if - met with a 10k drawdown - I'd be able to not tamper with the systems.
