I can't make out the indicators on the black background, but on your image #1, it looks like you have it right. The only difference must be that Alpari's prices at those points were different enough from other brokers prices at those moments, that you got different signals.
Two brokers whose prices have almost always given me the same signals as PipSurfer's are MIG Investments and Advised Trading.
Here's a shot of Advised from the same periods as your image #1. The trades taken at the same points would have had virtually the same results, but the signals appear different.
Hopefully helpful
