the worst thing a trader can do is "stalk" a paticular market whether its ES or their favorite stock, etc.
u have to be flexible
during a tulip bubble, u want to trade tulips
during a tech bubble, trade tech stocks
during a housing bubble, trade housing stocks
during sideways grinding bull market, sell premo
during an oil bubble, trade oil
proper market selection + proper position sizing makes this game a whole lot easier
don't be a stalker
