Ok... let me take it straight... you are not trading Silver but you are betting blindly on it... if it opened low does not mean it can go even lower... and if it opened higher no one can stop it from going even higher.
The major driver for Gold/Silver is the USD and its value... I never traded in Mini Silver so not sure if that is like Futures.. I believe that is. I trade silver in Spot Market so I can talk about that.
Silver is looking for a big correction in coming days or even months.. so watch out for a mid term trade and add some far month positions in the short side. Silver is one of the most rapid mover and it can burn your hands if you are on wrong side.
A quick example of what I meant and see what might have happened if you were on wrong side...
