Where will price go in the next 20 candles?

EMA20 (2034.91) is above EMA50 (2031.28), and the swing lows rose from 2020.49 to 2031.30 before a dip to 2028.94, so the uptrend was intact. Price pulled back to near the 2028.94 low and then closed at 2036.34, recovering above the EMA20 with buyers defending that area.

FAQ

Are the charts real?

Yes. Every chart is cut from real historical market prices. We never draw or edit candles.

How is the right answer decided?

By what actually happened next. After the last visible candle, if price moved up by 1.5× its normal range (ATR) before moving down by the same amount, the answer is BUY — and the other way round for SELL. Charts where price went nowhere are not used.

Is this financial advice?

No. BOS is a training game for reading charts. Past price moves do not guarantee future results. Never trade money you cannot afford to lose.
