These problems could ALL be solved by studying and researching to create a trading system and then extensively demo trading for at least 6-12 months until being consistently profitable for at least 6 months in demo trading and then trading LIVE with a programmed system so the least amount of your emotion would be involved.
The only thing you need to be careful with is that due to lack of reliable brokers, the execution quality in demo trading would be overwhelmingly superior than that of the real trading. So once you are consistently profitable in demo trading, try to find a reputable and reliable broker that would provide execution quality as close as that in demo trading.
