***PLEASE READ THIS BEFORE CONTINUING WITH THE VIDEO***

In this video, the topic was covered in regards to placing smaller size positions: up to 5 positions at a time.
I use this strategy when market isn't trending and I only want to hold about 5 positions.
Also, you would have to use this strategy (5 positions) if your trading capital is not large enough.

But when the market is trending and there are many setups available, I can hold 10-20+ positions.
When I hold this many positions, I would get into each position with much smaller percentage as explained below.

I suggest using below position-sizing strategy in regards to placing multiple positions: 10-20+ positions at a time.

* OPTIONS POSITION TRADING (6-10 months)
2% per Options position with 1% adding each time
(example: Buy SPY Calls as a fresh/new position - get in with 2% of your portfolio and then if you decide to add more to SPY, only add 1% at a time after that)

* COMMON SHARES INVESTING (2-3 Years)
About 5% to 10% per position with 3% adding each time
(example: Buy UAA shares as a fresh/new position - get in with 5% to 10% of your portfolio and then if you decide to buy more shares on UAA, only add 3% more)

* IMPORTANT: These numbers will vary based on my portfolio's health and capacity at the time of engagement. Sometimes there are many setups available,
if so, I would spread them out by buying three different stocks with 2-3% each instead of buying just one stock at 10%. 

* Portfolio Size
It's very important to understand the size of your portfolio. If you trade with smaller account, you are forced to go with higher percentage per position and may not able to hold too many positions.
Also you would have to pass up certain option setup, because it might be too expensive for your account.  
Keep in mind that you don't want one position to overpower rest of your positions, I always recommend lining the position with close to equal sizes.
Because you could have 5 positions going and if you put too much on one position, and if your other 4 positions are making money but that 1 position is losing, 
your overall account is now negative even though 4 of your positions are making money --- this is why position sizing is very important.
Always line up your positions in equal value.
