Despite me doubting the video and it's author 2% is 2%. If a bot makes 2% regularly with $1000, the only thing left to do is scale up capital. That's how percentages work.
What do you mean? Whether it's $1000 or $100,000, the algo will buy once the buy signal is triggered and sell for the sell signal. The market is not going to (all of a sudden) change course just because your algo is about to buy. The market doesn't care what you do.
I think that the word "regularly" is the critical point here. He mentions in his video that on the first day it made 4 USD. At the end of the second day the account had increased to 1023 USD. The following days the account value didn't change much, and he ended the week at about 1020 USD. So he had one lucky day during the week and no positive contributions during 4 out of 5 days. That does not sound like "regularly" to me, but more like a "one lucky hit" machine.
Now c'mon, we're talking about STOCK not FUTURES. Buying 100 shares of ABC stock will have no impact whatsoever and he would have no problem with his fill. If he was buying 100,000 shares, well, that's a different story.
I heard that it does not ( or read), but haven't checked myself, since my swings are from few weeks to few months. If you say that it does apply, when trading through european brokerages, US equities, then it does (?)
