还是这里论证下负反馈公式的详细推演数据。
举例论证公式效果,宽松目标负2%,即M=0.02,加速因子N=3
当溢价负0.04时(折扣4%),加速因子喂3。理想喂价 = BTS市场价 * (1-0.04+0.02)^3=BTS市场价 *0.98^3=BTS市场价 *0.9411,结论:市场价下调约6%,满意,也安全。
当溢价负0.03时(折扣3%),加速因子喂3。理想喂价 = BTS市场价 * (1-0.03+0.02)^3=BTS市场价 *0.99^3=BTS市场价 *0.97,结论:市场价下调约3%,满意,也安全。
当溢价负0.02时(折扣2%),加速因子喂3。理想喂价 = BTS市场价 * (1-0.02+0.02)^3=BTS市场价 *1^3=BTS市场价 *1,结论:目标达到理想状态,无需调整。
当溢价负0.01时(折扣1%),加速因子喂3。理想喂价 = BTS市场价 * (1-0.01+0.02)^3=BTS市场价 *1.01^3=BTS市场价 *1.030301,结论:市场价提高3%,接近理想目标。
当溢价0时,加速因子喂3。理想喂价 = BTS市场价 * (1+0.02)^3=BTS市场价 *1.02^3=BTS市场价 *1.0612,结论:市场价提高约6%,很满意,也很安全。
当溢价0.01时,加速因子喂3。理想喂价 = BTS市场价 * (1.01+0.02)^3=BTS市场价 *1.03^3=BTS市场价 *1.092727,结论:市场价提高约9.2%,满意,也很安全。
当溢价0.02时,加速因子喂3。理想喂价 = BTS市场价 * (1.02+0.02)^3=BTS市场价 *1.04^3=BTS市场价 *1.125,结论:市场价提高约12%,满意,也安全。
当溢价0.03时,加速因子喂3。理想喂价 = BTS市场价 * (1.03+0.02)^3=BTS市场价 *1.05^3=BTS市场价 *1.157625,结论:市场价提高约16%,满意,也安全。
当溢价0.04时,加速因子喂3。理想喂价 = BTS市场价 * (1.04+0.02)^3=BTS市场价 *1.06^3=BTS市场价 *1.191,结论:市场价提高约19%,满意,风险依然可控。
结论:溢价越大,喂价可以上调的空间越大,折扣越大,喂价下调的空间越大。
It is also the detailed deductive data of the negative feedback formula under this argument.
An example is given to demonstrate the formula effect. The loose target is minus 2%, that is, M=0.02, the acceleration factor N=3.
When the premium is negative 0.04 (discount 4%), the acceleration factor is 3. The ideal feeding price = BTS market price * 1-0.04+0.02) ^ 3 = BTS market price * 0.98 ^ 3 = BTS market price * 0.9411. Conclusion: The market price is reduced by about 6%, satisfactory and safe.
When the premium is negative 0.03 (discount 3%), the acceleration factor is 3. The ideal feeding price = BTS market price * 1-0.03+0.02) ^ 3 = BTS market price * 0.99 ^ 3 = BTS market price * 0.97. Conclusion: The market price is reduced by about 3%, satisfactory and safe.
When the premium is negative 0.02 (discount 2%), the acceleration factor is 3. The ideal feeding price = BTS market price * 1-0.02+0.02) ^ 3 = BTS market price * 1 ^ 3 = BTS market price * 1. Conclusion: The target is in an ideal state without adjustment.
When the premium is negative 0.01 (discount 1%), the acceleration factor is 3. Ideal feeding price = BTS market price * 1-0.01+0.02) ^ 3 = BTS market price * 1.01 ^ 3 = BTS market price * 1.030301, conclusion: the market price increases by 3%, close to the ideal target.
When the premium is 0, the acceleration factor is 3. Ideal feeding price = BTS market price * 1 + 0.02) ^ 3 = BTS market price * 1.02 ^ 3 = BTS market price * 1.0612, conclusion: the market price increase of about 6%, very satisfactory and safe.
When the premium is 0.01, the acceleration factor is 3. The ideal feeding price = BTS market price * 1.01 + 0.02) ^ 3 = BTS market price * 1.03 ^ 3 = BTS market price * 1.092727. Conclusion: The market price increases about 9.2%, satisfactory and safe.
When the premium is 0.02, the acceleration factor is 3. The ideal feeding price = BTS market price * 1.02 + 0.02) ^ 3 = BTS market price * 1.04 ^ 3 = BTS market price * 1.125. Conclusion: The market price increases about 12%, satisfactory and safe.
When the premium is 0.03, the acceleration factor is 3. The ideal feeding price = BTS market price * 1.03 + 0.02) ^ 3 = BTS market price * 1.05 ^ 3 = BTS market price * 1.157625. Conclusion: The increase of market price is about 16%, satisfactory and safe.
When the premium is 0.04, the acceleration factor is 3. The ideal feeding price = BTS market price * 1.04 + 0.02) ^ 3 = BTS market price * 1.06 ^ 3 = BTS market price * 1.191. Conclusion: The market price increases about 19%, satisfaction, risk is still controllable.
Conclusion: The bigger the premium, the bigger the space for feeding price to be raised, the bigger the discount, and the bigger the space for feeding price to be lowered.
