Made a noob-move, profited

So I just got a new comp at work and re-installed MT4 and all that. Of course no settings where saved and the default where set when it comes to opening a position. When I got the signals to go long I did so, noticing in the same instant that the trade was set that I forgot to change lot-size from 1 to my normal 0.02.

I was lucky and was able to close the position 2 pips later in the right direction. Making a 5% profit in 2 pips... my heart was halfway outside my chest.

Any noob-move you've done and gotten out on the right side of the 0-line?

Hahaha, o do I recognize that.

Last week I set up a trade where I was sure to make a profit, RSI way up, the price was sure to come down. But... it didn't, it just went up and up and I wanted to short. My order was active and I noticed the balance: - $400, - $415, etc all the way over -$1000. My heart sunk.

But I was convinced that it had to come down. I didn't want to stop the trade and take the loss it was simply too much.
And then it happened, I was drinking coffee, the price jumped down in a short spike, my trade came in the plus and my EA stopped it out: I made a profit of about $80. The funny thing is, it went up again but I left trading that day for what it was. That was enough excitement for me.

You know, there are no better moment in a traders life than 'mistakes' like these.
