Firstly eradicate such thoughts because one or another other day stock market could damage you financially. Have a positive thought for stock market and money will automatically flow to you.
Still, if you are unable to control your gambling urge, try following the 63: 37 ratio of hedging
Hedging can at least make you survive to some extent
If you are buying a call considering the market is going to go up buy only 63% of the call & hedge 37% buying a put
In case markets moving completely against your favor you can still get out in profits or no losses or with small profits or losses
It works well in current market conditions
Wednesday & Thursday are best days.
