The first few posts contain everything you need to know. Everything else is just us fluffin and goofin off.
This is a very risky system that should never be your primary system. Use very little lots compared to your trading account.
The system in a nutshell is just buy gbp/jpy going down and let the interest on drawdown build your balance and cash out your positive trades and buy again on downturns.
Most if all brokers are not paying swap right now on gbp/jpy, so this system is not going to work on guppy right now.
Also note that guppy can move 2k, 4k, 6k, even 10k pips in less than a year if she feels like it. So small lot sizes is key. The one major failure this system can have is users not knowing how important it is to keep a maximum of no more than about 2:1 leverage total on all open orders. So if you plan to buy up to 10 orders. Figure out what the total of the ten will make your true leverage 2:1. Then you will know what I mean when I tell you small lots. Most figure up the lot size using the above formula and don't want to bother even trading such small lots. Then they start trading larger lots than they should and make this their primary and only system. Next thing that comes is a blown account.
The failure and risk is not this system but the greed and misunderstanding that traders have using this system.
I too even got greedy and bought big tops in a falling market with this system. I was a lucky one. I only gave back most of my profits for the year and still closed out the year with a little profit. Looking back, I am so glad it happened. It thought me a great lesson on what the market is capable of doing and how fundamentals will always turn a market, even if severly lagging. Many who came here were not so fortunate.
Elijah, the creator of this system, has even been bitten a few times by his own greed. Maybe he will come back around soon and help me trade the kiwi.
