Hi, If you have gone short to Hedge (Dj Wall st @ 23800) against your free falling Long position (Dj Wall st @29350) and you now have a substantial profit on your short position, is it wise to cash in your profit to act as a cash buffer against a margin call, before the market reaches your short position at 23800, or is it better to keep the security of the Hedge and by doing so, let the profit erode? Probably a judgement call I know, but just looking for opinions and ideas? Cheers!
