Trading based on simple TDI rules

Anyone ever tested trading based only on simple TDI rules?
green>red: BUY
green<red: SELL

Sounds too easy to be true, and thus probably is, nevertheless I am fiddling with this in excel and am getting interesting results.

I am using M15 historical data EURUSD
Calculating RSI13 on close prices
Then calculating its 2-period SMA (green) and 7-period SMA (red).

Over a month (approx 1500 data points 24/7 trading) I get >4500 pips (LOL). Substract 2pip spread (approx 700 pips on 350 trades) and swap not accounted for, still a good result.
So, where is the bug...?

X.

Please attached the exact TDI indicator used for the backtesting.

I did not use the indi in MT4 yet.
Just manual calculation in excel of RSI and its SMAs.
Need to test it further when I get some time. Highly likely there's a formula error somewhere....

Not necessarily. Seems like you've kept it as simple as can be. Not worrying about the yellow and the blue lines and other things.

Can't really find an error in my calculations.
Forward testing today (if work allows )

Damn, there was an error (obviously).
So this is a no-go.
