关于BitMEX的杠杆

in #bitcoin6 years ago

在比特币降到6000$以下的时候,加密货币最忠实的信徒是怎样的心情?作为一个骑墙派,我不敢妄加揣测。不过,有一点是可以肯定的:把加密货币留在账户上然后去睡觉,神经衰弱的一系列症状大约会加重。

<p dir="auto">所以<a href="https://www.bitmex.com/register/O3rmQq" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">BitMEX(这里是个返利链接)用XBT计算盈亏就显得很有趣了:当比特币上涨的时候,大家都很开心;可是万一下跌的话,实际盈亏还要乘上汇率的缩水,一不小心就会得到双倍的悲伤。这种时候,理解账户数字的 <em>实际价值<sup><a href="#fn1" id="fnref1" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">[1],可能对控制风险有更为重要的价值。 <p dir="auto">根据<a href="https://www.bitmex.com/app/pnlGuide" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">官方指南,盈利的XBT数目可以这样计算: <pre><code>win_BTC_long=(1/price_before-1/price_after)*count #做多 win_BTC_short=(-1/price_before+1/price_after)*count #做空 <p dir="auto">那么,经过这部分操作之后,账户的最终价值是: <pre><code>win_BTC_long*price_after+cash/price_before*price_after #做多,或 win_BTC_short*price_after+cash/price_before*price_after #做空 <p dir="auto">其中,<code>cash是操作前账户的实际价值,<code>cash*leverage=count。 <p dir="auto">例如,当价格从1000$升至1250$,或从1250$降至1000$时,选用不同杠杆的盈亏如下: <div class="table-responsive"><table> <thead> <tr><th>leverage<th>作多,跌<th>作多,涨<th>作空,跌<th>作空,涨 <tbody> <tr><td>0.0<td>800.0<td>1250.0<td>800.0<td>1250.0 <tr><td>0.1<td>780.0<td>1275.0<td>820.0<td>1225.0 <tr><td>0.2<td>760.0<td>1300.0<td>840.0<td>1200.0 <tr><td>0.3<td>740.0<td>1325.0<td>860.0<td>1175.0 <tr><td>0.4<td>720.0<td>1350.0<td>880.0<td>1150.0 <tr><td>0.5<td>700.0<td>1375.0<td>900.0<td>1125.0 <tr><td>0.6<td>680.0<td>1400.0<td>920.0<td>1100.0 <tr><td>0.7<td>660.0<td>1425.0<td>940.0<td>1075.0 <tr><td>0.8<td>640.0<td>1450.0<td>960.0<td>1050.0 <tr><td>0.9<td>620.0<td>1475.0<td>980.0<td>1025.0 <tr><td>1.0<td>600.0<td>1500.0<td>1000.0<td>1000.0 <tr><td>1.1<td>580.0<td>1525.0<td>1020.0<td>975.0 <tr><td>1.2<td>560.0<td>1550.0<td>1040.0<td>950.0 <tr><td>1.3<td>540.0<td>1575.0<td>1060.0<td>925.0 <tr><td>1.4<td>520.0<td>1600.0<td>1080.0<td>900.0 <tr><td>1.5<td>500.0<td>1625.0<td>1100.0<td>875.0 <tr><td>1.6<td>480.0<td>1650.0<td>1120.0<td>850.0 <tr><td>1.7<td>460.0<td>1675.0<td>1140.0<td>825.0 <tr><td>1.8<td>440.0<td>1700.0<td>1160.0<td>800.0 <tr><td>1.9<td>420.0<td>1725.0<td>1180.0<td>775.0 <tr><td>2.0<td>400.0<td>1750.0<td>1200.0<td>750.0 <tr><td>2.1<td>380.0<td>1775.0<td>1220.0<td>725.0 <tr><td>2.2<td>360.0<td>1800.0<td>1240.0<td>700.0 <tr><td>2.3<td>340.0<td>1825.0<td>1260.0<td>675.0 <tr><td>2.4<td>320.0<td>1850.0<td>1280.0<td>650.0 <tr><td>2.5<td>300.0<td>1875.0<td>1300.0<td>625.0 <tr><td>2.6<td>280.0<td>1900.0<td>1320.0<td>600.0 <tr><td>2.7<td>260.0<td>1925.0<td>1340.0<td>575.0 <tr><td>2.8<td>240.0<td>1950.0<td>1360.0<td>550.0 <tr><td>2.9<td>220.0<td>1975.0<td>1380.0<td>525.0 <tr><td>3.0<td>200.0<td>2000.0<td>1400.0<td>500.0 <tr><td>3.1<td>180.0<td>2025.0<td>1420.0<td>475.0 <tr><td>3.2<td>160.0<td>2050.0<td>1440.0<td>450.0 <tr><td>3.3<td>140.0<td>2075.0<td>1460.0<td>425.0 <tr><td>3.4<td>120.0<td>2100.0<td>1480.0<td>400.0 <tr><td>3.5<td>100.0<td>2125.0<td>1500.0<td>375.0 <tr><td>3.6<td>80.0<td>2150.0<td>1520.0<td>350.0 <tr><td>3.7<td>60.0<td>2175.0<td>1540.0<td>325.0 <tr><td>3.8<td>40.0<td>2200.0<td>1560.0<td>300.0 <tr><td>3.9<td>20.0<td>2225.0<td>1580.0<td>275.0 <p dir="auto">这样,通过恰当地选择做多和做空杠杆,可以使做空和做多的回撤接近。比如说,同样是在1000到1250之间运动,做空2.5倍的最大亏损与做多0.9倍类似。如果在两个方向都使用2.5倍杠杆,可能会造成不必要的损失。 <p dir="auto">——当然,以上分析对比特币狂信者来说并没有什么意义。 <hr /> <ol> <li><p dir="auto">无意冒犯,这里的实际价值指的是能够换多少个比萨饼。 <a href="#fnref1" class="external_link" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog">↩
