@irishgold Over the years I've refined my stock list for options based on average volume of Open Interest, Volume, and Option Price... I trade Option Prices in the ~0.40 - ~2.00 range because when scalping there is a greater percentage of profit compared to higher priced options... So in order to be trading ITM or just OTM options the stock list becomes somewhat limited... I watch a total of about 25 symbols but some are for monitoring the current overall health of the market...
A short list of optionable symbols would be AAL, AAPL, AMD, BAC, CSCO, GDX, GLD, GOLD, MSFT, MU. NIO, PFE, SPY, SQQ, TLT, TNA, TWTR, UVXY, VIX, VXX, WFC, WMT...
A few others may get rotated in and a few of those may get rotated out depending on performance... Some of those symbols are far more volatile and risky than others, and some may not be good trading candidates over extended periods of time... Again, I'm watching for the underlying to pop and it's not uncommon to make 300% profit on a minutes long scalp...
But on the flip-side, if you don't have a good trading plan with stop-loss in place you can lose your entire investment... The covid crash last spring gutted my trading account when the markets plummeted and never recovered prior to expiration... Option prices fell below stop-losses and either sold at a huge loss or never traded so I couldn't exit and they expired worthless... The use of stop-loss is not a panacea when trading options... Those were swing trades and due to the losses I no longer hold any positions overnight unless I have a huge level of certainty that they will pop on the open...
I hope this information is found to be helpful...
