Let me just say that I find the idea that 5Dimes had a "technical issue" which caused the line to go in the wrong direction when OP bet it to be laughable. This is a core function of their site that seems to work just fine 99.9% of the time.
See below. OP said he saw the odds at higher values on successive days. He did not say that he watched the odds go up as he placed successive bets. In fact, he says the exact opposite of this. He clearly states that he bet a line down from +3500 to +1800 (BTW, this kind of movement is not at all abnormal if you have a marked account and are betting on futures at 5Dimes).
It's much more likely that other forces were causing the line to move in between OP's betting sessions. One of those forces could have been human error.
