ETH main decline wave 3 low point derivation:

Method 1: Referencing the retracement coefficients of the previous two waves.

Main decline wave 1: 4957 - 2620 = 2,337

Retracement coefficient 2337/4957 = 0.471

Main decline wave 2: 3403 - 1716 = 1,687

1687/2403 = 0.702

Using the adjustment coefficients 0.47 and 0.70, the retracement positions are:

Low point 1: 2463 - (2463 * 0.47) = 1,305
Low point 2: 2463 - (2463 * 0.70) = 738 (extreme low point, lower than the 2022 low, not used as reference)

Method 2: Fibonacci retracement derivation:

Main decline wave 2: 3045 - 1736 = 1,309

1309 * 0.382 = 500.038
1309 * 0.5 = 654.5
1309 * 0.618 = 808.962

Possible rebound levels:

1736 + 500 = 2,236
1736 + 654 = 2,390
1736 + 808 = 2,544

Actual high point: 2463

Gain: 2463 - 1736 = 727

Next wave retracement levels:

727 * 0.382 = 277.714
727 * 0.5 = 363.5
727 * 0.618 = 449.286
727 * 0.786 = 571.422
727 * 1.382 = 1,004.714
727 * 1.5 = 1,090.5
727 * 1.618 = 1,176.286

Below are the short-term support points:

2463 - 277 = 2,186 (Support Point 1)
2463 - 363 = 2,100 (Support Point 2)
2463 - 449 = 2,014 (Support Point 3)
2463 - 571 = 1,892 (Support Point 4)
2463 - 727 = 1,736 (Support Point 5)

All five of these support points have been tested and passed within the past three weeks.

After falling below 1700, the major bottom-fishing points (synchronous for futures and spot):

2463 - 1004 = 1,459 (Support Point 1)
2463 - 1090 = 1,373 (Support Point 2)
2463 - 1176 = 1,287 (Support Point 3)

For short-term futures trading, subdivided support points (preferably avoid shorting below 1600; even if it drops further, the decline won't be significant, be cautious of getting trapped at low levels):

1666, 1626/1606, 1556, 1512, 1444, 1368, 1288, 1146 (monthly Bollinger lower band, extreme low point)
