How I defined this support zone :
1/ Price rejection on the candle of Tuesday 24th of October at 7AM + another rejection at the candle of Thursday 26th of October at 11PM.
2/ a big green candle broke that resistance on the 27th of October at 3 PM, and price went down to re-test the zone after that.
3/ price went up after that, we see a nice candle which shows that price tried to go down but the buyers pushed the price (candle of the 30 October at 6AM). Price went up.
4/ now price is back to the same support zone.
