Coders, I'm struggling to find an EA (any EA) with a SL and TP based on last high or last low

[Daniel Cardoso]

We have tons of EA's around, but never with a smart SL and TP. My point is simple. When we place a trade, to place your SL you'll do one of these two options:
Use support and resistant previews levels, or.... chose a number of candle (e.g. the last 5 or 10 candles) and pick the lower low (in case of long trades) and lower lows (in case of short trades). My best trading system is made with HMA in the current chart to spot good entries and another HMA in a higher time frame, to pick the trend, and then this "adaptative" SL and TP. I know I little bit of coding, but have no time to work on this... if you're trying your coding skills, feel free to help us :)

Nice algo @nicholi shen .
I have to ask about the roundtick function . what is its purpose

#include <Trade\SymbolInfo.mqh>
CSymbolInfo _CSymbolInfo;
_CSymbolInfo.NormalizePrice(price);

Or simply copy and paste NormalizePrice from SymbolInfo.mqh.

It rounds to the tick-size of the instrument. It's common for CFDs to have a different tick-size than the "Point". If the prices aren't rounded it could fail on error.
