Needle: how FXNOD's Deriv Matches bot works

Needle at a glance

What Needle trades

Needle trades one contract only: Matches, from Deriv's Matches / Differs family, with a length of one tick. The contract is decided by the last digit of a tick's price, which is its final decimal digit: a tick at 1234.56 ends in 6. A trade wins when the next tick ends in the digit the bot picked. One digit out of ten wins, so a win pays several times the stake. A losing trade costs the whole stake. Deriv sets the payout, and each trade's result is listed on the run page.

When Needle enters a trade

Needle keeps a count of how many of the last 50 ticks ended in each digit from 0 to 9. At each entry it picks the digit with the lowest count and buys a one-tick Matches on it. When two digits are tied for the lowest count, it takes the lower digit, so the same ticks always give the same choice.

It needs the last 50 ticks of its market to make the count. After each result it lets two ticks pass, so entries are three ticks apart. The count is taken again at every entry, which means the digit can change from one trade to the next.

Needle holds one trade at a time: it looks for the next entry only after the last contract has closed. The entry rule sets when the bot trades and how often. It does not make any single trade more likely to win.

How Needle sizes its stake

Needle uses a Martingale stake. After a losing trade the stake is multiplied by 1.17; after a winning trade it returns to the starting stake. Losses in a row compound: the stake after two straight losses is the starting stake multiplied twice, rounded to two decimal places.

The stop loss bounds the ladder. A stake is placed only if it is no larger than what is left of the stop loss; a step that does not fit is not placed, and the session ends there. The table shows the stakes of an unbroken run of losses from a session that is level. A session that is already in profit has more room, and one that is behind has less.

Read the first row like this: on the stop loss 100 plan, 24 losing trades in a row cost 87.09 in total. The next stake would be 15.15, which is more than the 12.91 left of the stop loss, so the bot does not place it and the session ends.

The plans of Needle

Needle is not given a stake, a stop loss and a profit target one by one. You choose a plan, and the plan sets all of them together. Plans are named by their stop loss. The amounts are in the currency of the Deriv account the bot trades.

When a session ends

• The profit target is reached. The bot stops with the session's profit at or above the plan's target.
• The stop loss is reached. No stake is placed that could take the session's loss past the plan's stop loss.
• You stop it. The Stop button on the run page ends the session at any time.

Needle runs on FXNOD's servers, not in your browser. Closing the page or switching off your device does not stop it, and does not switch off its limits. Starting it again after a session has ended begins a new session with the full plan.
