回測有點問題，還有想寫停利停損不會寫

我有找到過去的文章有移動停利以下面為例，請問5是代表5%停損嗎?，

且移動起始點這個是指什麼意思呢? 是買入的價格嗎? 3代表什麼意思呢?

另外上面原本無法回測的問題，我剛剛重新按一次又恢復正常了

input: stop_per(5, "停損百分比"), trailing_per(3, "移動起始點");

var: stop_point(0), moving_point(0), controller(0);

if position = 0 and filled = 0 then setposition(1, market);

if filled > 0 and position > 0 then begin

    if controller = 0 then begin

        stop_point = filledAvgPrice * (1 - (0.01 * stop_per));    //計算停損點

    moving_point = filledAvgPrice * (1 + (0.01 * trailing_per));    //計算起始移動點

controller = 1;

end;

if close >= moving_point and (close * (1 - (0.01 * stop_per))) > stop_point then stop_point = (close * (1 - (0.01 * stop_per)))

// 如果價格大於起始移動點且新停損點大於舊停損點的話，更新停損點數值

    else if close <= stop_point then begin

// 收盤價小於停損點就出場

    setposition(0, market);

controller = 0;

print("out");

end;

print(date, time, close, filledAvgPrice, stop_point, moving_point);

end;
