post refresh wallets is overadding to pending deposits

[Exalovic]

People are experiencing the bot giving incorrect balances after the pending deposits update.

After looking at trade data I have identified that the function responsible for the problem is this one:

starts on line 268 in exchange.php

protected function postRefreshWallets( $tradesMade ) {
$id = $this->getID();
foreach ( $this->wallets as $coin => $balance ) {
if ( !isset( $this->walletsBackup[ $coin ] ) ) {
$this->walletsBackup[ $coin ] = 0;
}
if ( $balance != $this->walletsBackup[ $coin ] ) {
// Assume that a change in the balance when we aren't trading may be an incoming
// deposit being credited, look for one!
$change = $balance - $this->walletsBackup[ $coin ];
if ( isset( $tradesMade[ $id ][ $coin ] ) ) {
// If we have made a trade at this exchange of this coin, make sure to discount
// the change if it's less than the trade amount.
if ( abs( $change ) < abs( $tradesMade[ $id ][ $coin ] ) ) {
$change = 0;
} else {
$change += -$tradesMade[ $id ][ $coin ];
}
}
$pendingDeposit = Database::getPendingDeposit( $coin, $id );
if ( $pendingDeposit > 0 && $change != 0 ) {
Database::savePendingDeposit( $coin, -$change, $id );
}
}
}
Database::saveWallets( $id, $this->wallets );

However I'm unsure how to deal with fixing it
