Which log should I be looking at for that information? I just added a new coin, and the market history is completely empty.

About an hour ago, all of my coin pairs "lost" the market history and now the charts are basically blank, except the last hour. I tried getting rid of all the files in the .leonardo directory, but that did not fix it. Even after I started a fresh Bittrex session.

I can't reliably manually trade without a market history in a chart!

My buddy turned me on to this software, and let me tell you. It is amazing. I just purchased a copy and gladly would have paid many, many more satoshis than was requested.

A 16-hour analysis of the demo version using Poloniex paper/fake trading, my overall portfolio value increased 2.063% from my initial 1 BTC investment (+0.04660786 BTC, at time of measure approx. $111.51 USD gained)!!

I won't say that I never adjusted the mArgin maker bot parameters, but for the most part, over a 14 altcoin pair spread, the mArgin maker was allowed to do its thing, and it does a very good job of it.

I cannot wait to use it for real trading tomorrow. 

I have many other programs running. BURST miner (minuscule resource usage, not noticeable outside of its deadline cycling), Firefox ~8 tabs (+YouTube), a wallet or two. I try not to do anything intensive on my Windows machine (I use a Mac for work).

Looking at Windows' built-in Resource Monitor, leonArdo never goes above ~25% CPU [when in the background] and ~35% CPU [when actively using] with around 20-30 threads going, and a memory usage of ~800MB at any given time. I currently have 14 coin pairs actively trading using the mArgin maker. It's really not that big of a deal right now just wondering -- if I get really serious with leonArdo, if I should have a dedicated machine with a Ryzen or Core i7 that I do not use for anything else?

What are the realistic system requirements for more than 15 coin pairs? Am I trying too hard?

The program doesn't crash or anything, but the GUI lags more and more as I add coins. I am interested in this because if I ran multiple exchanges and each exchange had tons of coin pairs, it could get pretty slow.
