Last 15-minute bar
Copy it from your M15 chart (a bar that has closed). Open and close are enough; high and low make the call slightly more accurate.
Extra options (optional)
Time of day, spread and volume help slightly. Left blank, average values are used.
Advanced: use many bars (CSV)
This version looks at a 96-bar history, so it needs at least 100 consecutive M15 bars. Columns: Time, Open, High, Low, Close, Volume, Spread. MT5 exports work too. Times are treated as UTC.
Why this call?
One pip = 0.0001, the usual unit for price moves. “Call accuracy” comes from test data the model never saw: calls this strong were right about that many times out of 100 (a coin flip is 50).
