While I love the sharing on the planks, these statements simply don't make any sense. Quite honestly, it is dumb dangerous - here's why:
If you trust in the procedure that you have chosen for picking your transactions (and its profitable in the long term), then how often you do it doesn't matter at all. If you're profitable, there is no reason to stop at any given moment (other than exhaustion or something like this ).
Let us take the case of a casino - that casino offers a slot machine that pays out 98% of your money (i.e. you may eliminate money in the long run) and another pays out 107% (i.e. you will win money in the long run).
I walk in and play the 98% machine with two draws of the handle. On the next pull, I win $500 - excellent! \\\\\I must become an expert at this! \\\\\
I walk in another day and play the 107% machine and shed both pulls. \\\\\Man, this machine stinks, steals all my money! \\\\\
Does that imply that I should come back and play with the 98% machine daily? Of course not, I shall only lose all of my money (albeit slowly with just two pulls daily ). If you knew the true odds of these machines, then you'd spend all your waking hours in the 107% machine. Of course you'd have ups drawbacks, but over time you'd be winning. And above all, there is absolutely no reason to stop playing. The longer you play, the more you win (it is a percent after all).
In other words, stopping after two transactions is absurd if you're profitable and unprofitable. If you cease after two trade along with your system is finally not profitable, then that egy will only give you a false sense of safety and that is a very dangerous thing. If you stop after two transactions and you're profitable, then there is an opportunity cost you're \\\\\paying\\\\\. Would you rather have 107% of 200 or $200,000? The more you put through a profitable method, the better off you are.
