拨头皮的定义

利用互联网或计算机的“报价延迟”，“多次”“故意”或“恶意”在分钟之内“重仓”进出，并且在短时间之内赚取交易平台非市场价格的价差。

拨头皮实例

李先生在交易时，桌面同时有路透和英皇的报价，在早上10点钟时，李先生突然看到欧元对美元的报价分别为；

Reuters 1.1820/25
英皇 1.1821/26
Fuhui 1.1800/05

这时李先生觉得机不可失，因为福汇的价格明显的比其他两家来的延迟，他很清楚的知道，福汇的价格很快就会跟上其他两家的价格，于是就在福汇的交易平台重仓买入欧元，然后在1分钟后等福汇的价格跟上后平仓。由于福汇是自动交易，所有的下单都能保证按价成交，所以李先生食随知味，一再而三利用此手法大量获利。于是，这样的客户就会引起我们交易员的注意，而将该客户的自动报价转成手动报价。

这样的客户，交易商大都不欢迎，但是您的做法不是在于赚取市场的价差，目前来说，每间公司处理的情形不一，大概分成下列三种；


1.请您撤户，表明不欢迎和您做生意了。
2.干脆将您这笔单锁住，不让你平仓。
3.不保证点差，不保证到价成交。

所以建议大家不要做这种拨头皮的交易，风险很大。
