1. Chip peak setting
First, open the Flush client, find Chip Peak, and click the Settings button.
At this time, open the pop-up box as follows, in which the [chip distribution] formula is what you need to modify (my chip distribution ismodified);
You can search for "CM" in the upper left corner, select [Cost Distribution (System)], and then [Usage Instructions] will appear in the lower left corner, as shown below;
含义：用于画筹码成交分布云。
例如：CM(0,1,2,0,1000,1,0,0,0,1)
参数含义：
1、计算总天数：0表示计算全部天数。
2、当日成本算法：平均分布为0，三角分布为1。
3、精度：一般是2。
4、起始位置：0是从当天开始计算,1是从前一天开始算,类推。
5、换手：默认为100000%换手。
6、计算方式：按成交量计算为1，按成交金额计算为2。
7、筹码计算价格限制的最大值：默认为0。
8、筹码计算价格限制的最小值：默认为0。
9、功能切换：0表示筹码分布和火焰山（自定义天数前的筹码云），1表示活跃度（自定义天数内的筹码云）。
10、历史换手衰减系数：默认为1，可取0.1~10之间的数值。
As can be seen from the above description, the 10th parameter in the CM() function is 历史换手衰减系数, so only the 10th parameter needs to be modified.
2. Calculation of historical handover attenuation coefficient
We know that chip distribution studies the distribution of holding costs of circulating stocks. Tradable shares refer to the shares of listed companies that can be traded normally in the trading market, while the corresponding non-tradable shares cannot be freely bought and sold in the trading market. However, among the tradable shares, some stocks have non-tradable characteristics.
According to the "Several Provisions on the Reduction of Shareholdings by Shareholders, Directors, Supervisors and Senior Management of Listed Companies", the controlling shareholders of listed companies and< a i=3>Shareholders holding more than 5% of the shares,Directors, supervisors and senior management plan to reduce their shareholdings through centralized bidding transactions on the stock exchange, should report to the stock exchange 15 trading days before the first sale and disclose the reduction plan in advance, which shall be filed by the stock exchange.
换手率计算公式：
换手率 =（成交量 / 流通股本）x 100%
历史换手衰减系数计算公式：
历史换手衰减系数 = 1 / （1 - 前十大流通股东累计持股大于5%）
[Cumulative shareholdings of the top ten tradable shareholders] can be viewed from F10 of Tonghuashun, as shown below
Calculation results of historical hand-changing attenuation coefficient:
| Cumulative shareholdings of the top ten tradable shareholders | Historical change of hands attenuation coefficient |

| 5% | 1.05 |
| 10% | 1.11 |
| 15% | 1.18 |
| 20% | 1.25 |
| 25% | 1.33 |
| 30% | 1.43 |
| 35% | 1.54 |
| 40% | 1.67 |
| 45% | 1.82 |
| 50% | 2 |
| 55% | 2.22 |
| 60% | 2.50 |
| 65% | 2.86 |
| 70% | 3.33 |
| 75% | 4 |
| 80% | 5 |
| 85% | 6.67 |
| 90% | 10 |
