#04 Trying out "Nanchatte EA"
October 13, 2025: Note
I have finally ported external historical data to MT4, so I'm going to test whether the EA will run.
Since it just needs to move, I’ll use a very rough, improvised logic.
Pseud EA – Logic (lol)
0.
Capital: 100,000 yen. Order size: 0.01 lots. Period: 2024-10-05 to 2025-10-04
1.
Sell short at the opening price of the most recent bullish candle that is closest in time to now (hereafter called “target”).
Record the target’s lowest and highest prices.
2.
Do not open a new position until the current one is closed.
3.
If you hold a position, close when the target reaches its low or high.
4.
If the above “3.” is not hit, when the current candle finishes, close at the open price of the next candle.
“4.” should really be: close at 23:59:50 if none of the above is hit, but I only have daily data now, so I gave up.
This is only a test to see if the EA runs...
※ Why would I want to “close at 23:59:50”?
Because if markets gap on Monday, it would cause massive losses.
Well, this time it’s fine (laugh)
Anyway, I’ll paste the code for now.

→ Next, in MT4's MetaEditor, create a new Expert Advisor and paste the above code.
→ Click the "Compile" button to ensure there are no errors.
→ In MT4, select this EA in the Strategy Tester and run a backtest.
