using namespace std;
using namespace eosio;

class [[eosio::contract("test")]] test:public eosio::contract{
    private:
        void make_transfer(name& from,name& to,asset& quantity,string& memo)
        {
            token::transfer_action transfer{"eosio.token"_n, {from, "active"_n}};
            transfer.send(from,to,quantity, memo);
        }

    public:
        test(name receiver,name code,datastream <const char*> ds):contract(receiver,code,ds){}
        [[eosio::action]]
        void trade(name from,name to ,asset fromcoin,asset tocoin,string memo)
