The inputs for the special orders (such as SetStopLoss, SetProfitTarget, etc.) are treated in the Base Currency selected in Format->Strategy Properties->Properties.
If you want them to be treated in the currency of the symbol you need to use MultiCharts 9.1 or above and change the setting in the Windows Registry editor. Go to HKEY_CURRENT_USER\Software\TS Support\your MultiCharts version\StrategyProp and create a key SpecOrdersAmountIsStrategyCurr.
0 - calculate amount in instrument's currency.
1 - calculate amount in strategy/portfolio currency.
Basically this is described in the help file for the command in the PowerLanguage editor.
