How do you setup commissions for forex in wealth-lab developer 5.1 ? I want to setup my own commission structure which attaches a different commission depending on the contract traded, i have checked the user-guide and wealth-script programming guide and they are no help.

In Wealth-Lab V5, commission structures are implemented in external dynamically linked libraries (for instance, the two currently existing options are coming from Community.Commissions.dll). However, versions 5.0 and 5.1 were somewhat limited in that users cannot select or store options. When it's fixed, we're going to have more flexibility and will finally see more commission plans. At that time, you'll notice an update available to Community.Commissions in the Extension Manager.

You may tell us about your forex commission structure so that when the time comes we would have a reference point.

Well basically in my forex there is no commission, but there is spread, which is effectively a commission anyway. Different forex have different spreads so each needs to be treated differently, also, depending on the time of the day when various markets are open/closed there is also a different spread and effectively a different commission

Broadly speaking, you could use slippage for that. As long as you entered your forex symbols as futures symbols in the Symbol Info Manager and enabled futures mode, each slippage unit represents a single tick (i.e. forex pip). Problem is, there's only one value which is global, despite your currency pairs have different spreads.
