PeakeCoin BNB Trading Bot - Stop Loss Logic

So here working on the @PeakeCoin project we have had a couple things to hold us off a little bit. Since its currently just me expanding my own work portfolio, so hopefully I can score some side jobs and not have to really have ajob anymore, lol.

Seriously though lets get back to business.

I was not losing money, but the logic was only set to a percentage that was off of the last buy/sell price. Leaving it at that point doesn't really guarantee a profit for any of the transactions.

So with the existing trading bot https://ecency.com/hive-167922/@paulmoon410/peakcoin-bnb-trading-bot only had the logic of percentage offset of the last orderbook

TOKEN = "SWAP.BNB"
SPREAD = 0.01  # 3% above/below for placing orders
TRADE_QTY = 0.001
SLEEP_TIME = 60  # seconds

def trading_bot():
    while True:
        book = get_orderbook_top(TOKEN)
        if not book:
            print("❌ Failed to fetch orderbook.")
            time.sleep(SLEEP_TIME)
            continue

        buy_price = book["highestBid"] * (1 - SPREAD)
        sell_price = book["lowestAsk"] * (1 + SPREAD)

What I've been trying to accomplish is more along these lines.

TRADE_HISTORY_FILE = "trade_history.json"
MIN_PROFIT_MARGIN = 0.015  # 1.5%

def load_trade_history():
    if os.path.exists(TRADE_HISTORY_FILE):
        with open(TRADE_HISTORY_FILE, "r") as f:
            return json.load(f)
    return {}

def save_trade_history(data):
    with open(TRADE_HISTORY_FILE, "w") as f:
        json.dump(data, f, indent=2)

def update_trade_history(token, action, price):
    history = load_trade_history()
    if token not in history:
        history[token] = {}
    history[token][action] = price
    save_trade_history(history)

Within the logic of the stop/loss code

    history = load_trade_history()

    if order_type == "sell":
        last_buy = history.get(token, {}).get("buy", 0)
        min_sell_price = last_buy * (1 + MIN_PROFIT_MARGIN)
        if price < min_sell_price:
            print(f"🚫 Skipping SELL order — price too low to make profit. Minimum: {min_sell_price}")
            return False
    elif order_type == "buy":
        # Optional: prevent buying above previous sell price
        last_sell = history.get(token, {}).get("sell", float("inf"))
        max_buy_price = last_sell * (1 - MIN_PROFIT_MARGIN)
        if price > max_buy_price:
            print(f"🚫 Skipping BUY order — price too high to profit. Maximum: {max_buy_price}")
            return False

I'll update the Github place_order.py with the @peakecoin.bnb bot within the next few hours. I haven't run a new bot with the code I've posted here to date. If it doesn't work, I'll post the corrective pieces of the code. I'll post them tomorrow if I fix it, or if you fix it let me know.
