The back tester ONLY shows BOT profit /loss (In my case i use USDT) and does not show profit/loss for the base coin. This is a big flaw and effectively makes back tests invalid. We only have 50% of the required information. In a bear market we can have significant loss because the grid bot buys 50% of the investment at the start of the trade, and we could keep buying in a decling market. To ignore this makes the back tester invalid
Other suggestions:
I need to know the Maximum draw down during the trade. I want to know the risk profile.
Also Bitsgap could add a dummy account so that we can run bots to test we are pressing the right buttons. This uses bandwidth on your server, simply charge a flat fee say $5 per month. Maybe after 3 months when we have masteres the bots its not required. Your initial test period is inadequate. The options can be complex.

1000% Agree.
