“PAMM Account is an investment service that gives investors the chance to make money without trading themselves on Forex and allows managers to earn additional income for managing client funds.”

“The Manager designs his Proposal, in which he lists the terms for investors. This includes the percentage of their share of the profit they will pay him in compensation.”

上面的链接有非常清楚说明。

基于原文 PAMM 是一种投资方式， 通过投资经理的建议 (investment offer) ，客户可选择哪个投资项目较适合他们，然后决定投资。因此经理会写出各种投资条件的信息 （terms for investors) 如下：

Trading interval －交易长短
Minimum deposit － 最少按金
Minimum withdrawal － 最少提款
Fees － 佣金（给 manager)

每个manager 都可以展示其各种投资建议，客户只需在网上研究好 manager 的投资表现，才决定选择光顾哪位。

所以，我觉得这个 offer 就是 “投资建议”。

于这语境下，应并无他意，足够表达此词语的意思。

供参考。
