Cardano retreated below $0.250 on Monday after gaining more than 11% over the preceding week, with ADA changing hands near $0.245. The pullback followed a September 28 advance that took the token near $0.2537, with a later quote at $0.25691420, but ADA remained above several closely watched technical levels. The $0.26 area remained a key resistance zone, while $0.25 and then $0.20 were identified as support levels if selling intensified. Earlier derivatives data showed falling trading volume, futures open interest and options activity, alongside a low long-to-short ratio and positive funding rate. Cardano decentralized-exchange turnover had surged, while CryptoQuant identified whale-sized futures orders and sell-side pressure following the rally.
