告诉我你的想法 (tell me what you think)

I'm kind of new to forex, been doing demo's for over a year. right now i have a mini account open with fxcm. their charts don't offer most of the indicators you guys use in your system so i'm trying to figure out one that i can use with the indicators available to me. right now i'm trying out this one:

macd-12,26,9
SAR
moving averages 18 and 36

I wait for all 3 to give an indicator before i enter a trade. if someone could backtest that for me that would be great. i use the 15 minute chart with it.

also i have an idea for a bot, but of course i have no programming skills. the bot would run like this: it would enter a trade every minute. whether it goes short or long depends on the color of the previous minute's candle. if it was red, then it goes short, blue or green and it goes long. it would require using a broker that offers a 0 pip spread, or maybe even one. http://neuimex.com/?id=36 this company offers a 0 pip spread on eur/usd. every trade would have a sl of 2 pips and a tp of 3 or 4. although when i first thought of it i thought maybe a stop loss at 1 a take profit of 2. it makes sense to me because if you look at a one minute chart you'll see several reds or several blues (or greens) in a row.

Any input on my current system or on my idea for a bot would be appreciated.
