Sounds like a great idea. Honestly, I do not have a good suggestion for the bot yet, but I'll let you know when I think of one!
Maybe looking at the price&volume at another exchange? If there's a much higher volume on an other exchange and the price is also quite different, it could be falling/rising. That could be a nice addition.
Also, you said it trades 10 pairs, but the guy that said "3 pairs", meant Arbitrage Trading, which is using price differences between different pairs to obtain an almost risk-free profit. For example:
Buy 10 litecoin for $50/each, so $500.
Buy 2 Bitcoins for 5 Litecoins each, so 10 Litecoins.
Sell 2 Bitcoins for $275 each, so $550.
You just made 10% profit!!!
Obviously, it won't be that easy and profitable in reality, but it was just an example.. You get the idea.. I hope?
