Wait a second, I see Heiken Ashi only in the title 
Few weeks ago I added Heiken Ashi indicator to the built-in indicators with few extra options for it. I think it covers this situation where you want to find bull-bear-bear or bear-bull-bull candles. But the candles of the indicator are read and white in color.
You are showing me regular candles. Well, there is no single block where you can specify order of candle colors, but I think this can be done with 2 or maximum 3 blocks like Condition or Bears/Bulls in a row.
About the lot size... what kind of lot size is 200.000? Maybe 0.2 lots, or maybe you are working with some of those symbols I have never heard
Anyway, there are some Money Management options you can try. If none of them works, you can use the default one and insted "0.1" you can write any formula that includes MQL4 functions like AccountBalance(), AccountEquity() or others. I often do that actually
For "Fixed volume" the expected value is something like 0.1 and I can write something like *AccountBalance()2/10000, which will give me 0.2 if I have 1000 dollars.
