Would you usually hang onto a bet that long if it only scaled one higher high in 5 or 6 trading days forexspot?
It’s by no means criticism of your activity because I have no idea what your performance data records show for this type of gamble, but don’t lose sight of what this approach is all about. You’re seeking confirmation of shifts in [B]dominant[/B] directional momentum.
If that shift begins to fade & dissipate then might your efforts & financial outlay merit keener value elsewhere until your focal pair begins exhibiting the type of behavior you’re seeking? Just a suggestion.
Don’t be afraid to cut, run & redistribute if a currency or pair isn’t performing as you expect, because there will likely be another 2 or 3 candidates showing more promise & if your focal pair decides to go on a bit of a jog you can run alongside it whenever you choose to by hopping on via the pullbacks.
As skip (on the bid) rightly advises, you should always adhere to your pre-entry plan whenever circumstances take a turn for the worse because as you correctly state, no-one knows where the eventual price will bounce or ease following an erroneous, rogue or price influenced shift.
Quite often, if the move is influenced by, or attracted to an area containing a mish mash of stop orders or a big round number for instance which more often than not is a magnet for options traffic, once the orders settle & aggregate you often witness a resumption of the dominant cycle as was the case in your AUDNZD example of the 27th February.
This typical scenario will usually offer you another opportunity to engage via a pullback or breakout trigger as prices attack & consume a prior day or week high/low level. If the dominant theme fails to resume your stake is free to pursue a similar behavioral set up on another dominant/passive pairing.
If your data records show a positive pattern & expectancy tracking & trailing your bets in the manner which you’ve presented then carry on in that vein & take the guys advices about ignoring other posters preferred stance & stick to your own tried & tested game plan.
