Thats easy, the drop-loss price looks to the current price and once it sees the current price is crossing the drop-loss price it will try to sell the coins. At a drop you want to sell for the current prices so thats what the software does, it looks for the current sell price and it creates a order based on that.

So the difference you see is normal, it is a minor draw-back that will almost ensure your coins being sold. If the software would have tried to sell for the higher price it is almost fully to be expected your order will not get filled. (in other words, you will be getting much bigger losses)

@all:
There is a minor bug detected into the "Price Change" indicator. I do recommend NOT to use this indicator. The indicator, as it is now, will allow a buy signal to soon. So unless you use more indicators you could get to high buy prices.

The problem is fixed already for the new release, but there are 2 other things i will have a look at first before i put the new release online. I do not want to keep updating unless it is absolutely needed.
