PLUGIN THAT OPENS MULTI-CURRENCY PAIR AT ONCE

I am trying to create a plugin or cBot that has two button icons named A having green colour and the other name B having red colour. When I click the A button, it should place buy order for GBPUSD, EURUSD, XAUUSD, AUDUSD and place sell order for USDJPY, USDCHF. When I click the B button, it should place sell order for GBPUSD, EURUSD, XAUUSD, AUDUSD and buy order for USDJPY, USDCHF. use 2.5% of the equity for placing order for each pair.

I have tried and at this this point it keeps giving error about definition for the key not existing.
