Hi IGHOR!
First I really want to thank you for QtTrader - and for the fact you're offering it for free so far (thou I would have no problem with paying for it in form of tiny transaction fees or when proved profitable, even for a price)
It has a value for me even for simple manual trading, but I can't make my idea of automation work - which I think is what this app would really shine in.
My idea is:
1) to make consecutive buy/sell orders across the market estimated fluctuation e.g. 350-1000 USD/BTC, with let's say 0.62% margin between trades (partially done already, works)
2) then sell high, buy low, with sell/buy orders being made automatically by bot, as the above orders are being filled as the price rises/lowers, e.g.: 455(buy)->450(buy, make sell order at 455)->455(sell, make buy order at 450) etc.

The problem is, I'm unable to set the rule for the condition "after a sell/buy order was being filled", because:
-IF-> "My orders last buy/sell price" -> "Goes More Than/Goes Less Than" -> "percentage" - seems not working at all for me - there's just no reaction. And since there's no "Goes Less BY/Goes More BY", only "Goes More OR Less by", I don't see how to possibly use this rule.
-The roundabout for this - IF BTC/USD balance" -> "More or less by" -> "Exact value" - doesn't work, because it seems to pick the change of balance of the order just being made by the rule itself or it stops working at all for some reason after a while.
-The "Market last price" rule, if used as the ones above - the results were unpredictable, thus for automation it seems unusable.

Thus the only reference for automation is the "Exact value", i.e. exact Market price, which seems unusable on the bigger scale - as more than hundred of orders are being made.

So I would like to know, if the above behaviour are indeed bugs, or if I'm the one who's doing something wrong.

Also I noticed what seems like some minor bugs/inconveniences:
-making new group by copying a previous group sometimes makes a copy of the wrong group
-all rules groups are set to "sequential" by default upon closing and reloading the application.

Please correct me, if I'm wrong in my assumptions, as I'm a newcomer into BTC Trading. Also I apologize if I misunderstood something, or if those are already known issues.
Cheers!
