Yes. Hedging was prevented in the original script by not opening a trade when another one was still open, but when extending the life time of a trade, you must disable hedging explicitely. The same goes for other settings, for instance you must explicitely set the payout and reset spread and commission for any asset when you binary trade a portfolio - that was an issue in another thread here.

Zorro does not do those things automatically. The binary mode was added as an afterthought and is no native trade mode, so you must be careful to avoid contradicting settings.
