Have you been testing the software on a live account? If so, for how long, what was the initial deposit, what what is the current balance, what is the current equity, and what % was the largest drawdown?
As a broker, you can easily do one think that rarely is an option for an ordinary trader. Ask your LP(s) to examine the trades the account has been making to make sure that none of them could later be disallowed as arbitrage. There's no point turning $10,000 in $6 billion, or even $10,001 if your LP declares the trades aren't valid and won't pay.
I also sugggest finding several other regulated brokers with tight spreads to test it on. After all, your LP might be happy early on, but later realize that the bot is "too profitable" for the LP to support.
I'm now going to surprise you. I never wanted a copy of the bot or algo. I only wanted to be able to verify live results via the investor password at some well regulated (and preferably also well-rated) brokers. Backtests and even demo forward tests can not prove that a bot is profitable. They can only show if it is worth risking a reasonable amount of cash on a live test.
Also, I'm not a coder, but I do know that some very clever EAs had been specially rigged so that backests automatically excluded opening trades at times when the bot would have had taken significant losses. Unless the coding was extremely blatant about this, I doubt I could spot it even if I printed the whole thing out and went through it line by line.
Additionally, whether it really works perfectly, is some form of rigged backtest scam, or falls somewhere between those 2 extremes doesn't remove copyright. Depending on the terms of your deal with the so-called hedge fund managers (or freelance bot sellers who claim to be hedge fund managers - since real hedge fund managers who found the holy grail would be very unlikely to sell it on a freelancer site) may not have granted you the legal right to share it.
What I can recommend instead is that you hire a professional trading bot coder to examine the code and but it through some very thorough testing. Hiring a consultant to test and examine a product is far less likely to violate copyright law (and hopefully won't violate whatever contract you did sign to get the software) than handing a copy over to me to play with.
There are a number of
trading software developers in the FPA's reviews. You are free to chose anyone you like for this, but let me point one out to you. Rimantas Petrauskas not only has
good ratings at the FPA, but also has published a short book with videos about some of the
common scams used to sell trading bots, signals, and indicators here at the FPA. If he can't help you, he may be able to recommend someone who can.
