Hi thinking of buying but have a few ?s

Security? how safe is this to use I did not find any posts talking about this, Who can see my keys? can the developer see or get access to an exchange account? what protection is in place to stop this and keep things safe?

I too am kinda waiting for the Kraken version how far out is that I also use Bittrex for the newer alt coins But I like to trade USDT to what ever the most.
When the Kraken version is out will it support the trailing stops?

Using the ping pong feature can this run all day buying and selling only taking a small profit on small movements when it is going sideways with out the exchange having a problem with that many buys and sells going on.?

I just DL the newest version and it has already crashed the version before this I never had a crash. I am on win 7 64 bit
Also, i can not seem to move around the candle stick area like I see in the videos nothing moves for me.

Thanks
