Is the papertrader accurate?

[redquicksilver]

Please could you help me understand how the paper trader gets it's buy and sell figures as I fail to see the comparison to the figures it produces and real live data from the exchange I am using, for instance:

A paper trader running last night for EUR-ETH on GDAX gives:

2018-01-09 02:36       2018-01-09 05:33       3 hours            947.404            957.339         9.94              1.05%


However looking at GDAX and the closing price for those times shows:

2018-01-09 02:36       2018-01-09 05:33       3 hours            986.09            996.93     



The actual cross-over points are accurate to the minute for the testing that I have done, however the figures are wildly inaccurate unless I am reading it wrong.

Please would it be possible for a developer to shed any light on this, and if possible give me a rough idea of how it works as I am developer myself, (with over 25 years experience) and will look into this and repair if you think it is in fact incorrect, and would be happy to share my update with you if you deem it fit.

Many thanks,
Stephen

The paper calculated based on the close price of the candle to which the strategy emitted advice (but applies configured fees as well).

However looking at GDAX and the closing price for those times shows:

2018-01-09 02:36       2018-01-09 05:33       3 hours            986.09            996.93     

Where did you get these prices from?
