If is set stoploss as lowest of 10 candles before and set tp as 50% of stoploss, what happens? the code evaluates the pips or values automatically? because lowest of 10 before candle is a number and 50% of this number may be in another range of prices. I'm in a daze!

I use custom properties and use highest/lowest price candle id for stop loss. Then I use it as pips.
For example if I set period of candles between 1 and 5 and then use lowest price as pips, what is the output? Is it give me the maximum pips in this period or give me other things?

Hi
I want to put a buy order. for example when candle cross up MA20 buy. then sell it when candle cross down MA20. how can set this? how can set take profit on this way?
