The key signal is not the earlier push to 613.5, but the late-session reversal into a 599 close with a very heavy 44.4 million-lot final print, which points to distribution rather than follow-through. The daily and weekly structures both show momentum loss: after 625.5 and 617.5 peaks, price is now closing near the lower end of the recent range. The order book is asymmetric, with buy concentration around 599-595, while layered sell supply sits from 603 to 606.5 and is being absorbed above 600. Today’s cash turnover of 473.9 million TL is lower than prior sessions, yet the market still finished weak, which increases the importance of downside pressure per unit of volume. Intraday action after 13:55 shows a sharp fade from the day’s high, accompanied by large-volume bars, a classic sign of short-term supply dominance. The news flow is neutral and does not provide a fresh catalyst strong enough to explain the move. In synthesis, the dominant anomaly is a combination of intraday distribution, overhead sell stacking, and a breakdown in closing momentum.
