In trading you're in the risk management business. So, keep the trade size small, say 1% of total equity. This ensured you can't blow up quickly and stay in the game in the long term (google 90/90/90 rule). But before you trade real money, develop a strategy and back-test it. No eye-balling but systematic back-test to see whether it works or not, what the drawdowns/risks are. Can be done with a few simple scripts and for cash FX if you should be so inclined, you have not to worry about futures rolls.
When your system/approach has proven to be profitable after costs, then you can start with real money, again keep the trade size small.
Detach yourself from the monetary aspect. Trading is a business, no place for emotions (nb: so the more you automate or give the computer the better for that reason, also small bet size keeps emotions at bay).
Lastly, keep your costs under control. This applies to commission and platform costs. Keep things simple and low cost. There is so much mumbo-jumbo sold as "essential" etc which is so unnecessary. You just line the provider's pockets. (for my own biz which is not FX, I pay $2/lot, no platform fee, no data fee which perfectly suits my style and objective. I could have easily signed up for an all bells and whistles platform for 100 bucks a month before the first penny P&L).
Otherwise, good luck!
