Convert Pinescript into MQL5 auto trading robot with minor modification

Below is the script I want to convert to MT5 the only addition is that I want to add a way to each time trade the maximum of my balance or the amount traded must go up with the amount of the

// *** THIS IS JUST AN EXAMPLE OF STRATEGY RISK MANAGEMENT CODE IMPLEMENTATION ***

// === GENERAL INPUTS ===

// short ma

maFastLength   = input(defval = 14, title = "Fast MA Period", minval = 1)

// long ma

maSlowSource   = input(defval = open, title = "Slow MA Source")

maSlowLength   = input(defval = 21, title = "Slow MA Period", minval = 1)

// === STRATEGY RELATED INPUTS ===

// the risk management inputs

inpStopLoss     = input(defval = 200, title = "Stop Loss", minval = 0)

inpTrailStop    = input(defval = 200, title = "Trailing Stop Loss", minval = 0)

inpTrailOffset  = input(defval = 0, title = "Trailing Stop Loss Offset", minval = 0)

// === RISK MANAGEMENT VALUE PREP ===

// if an input is less than 1, assuming not wanted so we assign 'na' value to disable it.

useTakeProfit   = inpTakeProfit  >= 1 ? inpTakeProfit  : na

useStopLoss     = inpStopLoss    >= 1 ? inpStopLoss    : na

useTrailStop    = inpTrailStop   >= 1 ? inpTrailStop   : na

useTrailOffset  = inpTrailOffset >= 1 ? inpTrailOffset : na

// === SERIES SETUP ===

/// a couple of ma's..

maFast = ema(maFastSource, maFastLength)

maSlow = ema(maSlowSource, maSlowLength)

// === PLOTTING ===

fast = plot(maFast, title = "Fast MA", color = green, linewidth = 2, style = line, transp = 50)

slow = plot(maSlow, title = "Slow MA", color = red, linewidth = 2, style = line, transp = 50)

// === LOGIC ===

// is fast ma above slow ma?

aboveBelow = maFast >= maSlow ? true : false

// are we inverting our trade direction?

tradeDirection = tradeInvert ? aboveBelow ? false : true : aboveBelow ? true : false

// === STRATEGY - LONG POSITION EXECUTION ===

enterLong() => not tradeDirection[1] and tradeDirection // functions can be used to wrap up and work out complex conditions

exitLong() => tradeDirection[1] and not tradeDirection

strategy.entry(id = "Long", long = true, when = enterLong()) // use function or simple condition to decide when to get in

strategy.close(id = "Long", when = exitLong()) // ...and when to get out

// === STRATEGY - SHORT POSITION EXECUTION ===

enterShort() => tradeDirection[1] and not tradeDirection

exitShort() => not tradeDirection[1] and tradeDirection

strategy.entry(id = "Short", long = false, when = enterShort())

strategy.close(id = "Short", when = exitShort())

// === STRATEGY RISK MANAGEMENT EXECUTION ===

// finally, make use of all the earlier values we got prepped
