The transaction was successful in the iota network. But on the stock exchange's deposit, nothing came I sent a request to the support service Proved that I sent an iota to the right address. No explanation yet.
I've had a look at on the block explorer and can't see it showing any confirmations of the transaction (should it ?).
If your transaction does not confirm (is still shown as pending), you can Rebroadcast it
