check your bots preferences > email.
you can define weather the bot should send you an email when orders are imminent (=your threshold is shortly before triggering a buy/sell order) and/or when orders are actually triggered (=bot is buying/selling).
the 'imminent' warning makes sense in case you want to transfer additional funds to your exchange.
so it would be safe to assume i was on the verge of hitting my threshold and than something happened where my threshold was never reached therefore never triggering a purchase?
one other question is there any plans in the future to add additional currency pairs support? such as LTC->USD ; LTC->BTC?
