anything out that will do LTC or alt-coins at all ??
Gekko has plans, but those are deffered until the new BTC-e API stabilizes.
With backtesting on this I found 0.80/0.80 was better... thus perhaps best to change the gekko config file to:
"
sellTreshold: -0.80,
buyTreshold: 0.80
"
?
"
sellTreshold: -0.80,
buyTreshold: 0.80
"
?
Good idea, I'll look into what will be nice beginner settings. But I do need to make it clear that Gekko is more an trading algo platform then something that works out of the box.

I like it a lot actually, this way the bot doesn't change position as agressive as the default one which saves a lot in fees. But this also means that the bot may not pick up light trends.
I am running a couple of paper traders but my real trading Gekko has thresholds of -0.9 and 0.4 (with other EMA short & long) as it appeared very stable over the last couple of weeks.

By the way, I wanted to use your backtester to verify my EMA and backtesting implementation. But I can't find the raw candle date. How did you calculate your candles? Similar to my candle fetcher (which uses the trade data MtGox put in Google BigQuery)?
